My partner keeps feeding our baby bigger
For reference only. Not medical advice.
Question
My partner keeps feeding our baby bigger bottles and then she spits up and cries. How can we tell if a baby is being overfed? Real household: caregiver juggling school week and one elder or sibling nearby. Schedule: Sat; during the evening bottle. Kitchen/home right now: paced bottle feeding and watching hunger cues. Already tried: offering a bottle every time she cries. Please answer as a practical family-care guide: what to do next tonight/today, what to avoid, and a clear decision tree. Constraints: respect «No diagnosis, no medication changes»; no dosing kids/pets/elders yourself; no mystery powders or buying prescription meds online; keep steps screenshot-friendly under ~25 minutes where cooking/care applies. Structure your help as (1) what I already tried vs better alternatives, (2) constraints/avoid list, (3) red flags—when to stop DIY and get clinical/urgent help. Keep the voice concrete and kind for a tired caregiver; stay inside kitchen/home-care/communication levers only. Name what success looks like in 24 hours without promising cures. Avoid brand shopping lists; focus on routines, food already at home, and communication scripts caregivers can screenshot.
Answer
Tonight, run the next two or three bottles by the baby's cues instead of the bottle size: hold her semi-upright, let her set the pace, and stop the moment she shows she is done — a feed that ends with her turning away is a win, not a failure.
Below is how to tell "she had enough" from "something else is wrong", what to do in the next 25 minutes, and the two lists you asked for: what to avoid, and when to stop home care. I cannot diagnose and this is not a diagnosis; I also change nothing about her volumes or her medicines — those belong to the clinician who sees her.
1) What you tried vs. a better alternative
What you tried: a bigger bottle whenever she cried. The trap is that a cry after a feed is ambiguous — fussiness is also on the list of symptoms of milk coming back up (NHS, *Reflux in babies*, checked 24 October 2026). So "cry = feed" can quietly add volume she did not ask for, and more volume is exactly what her body then pushes back out.
Read the cues, not the cry. Signs she has had enough:
- closes her mouth, or turns her head away from the teat
- pushes the teat away with her tongue or her hand
- her hands relax and go floppy
- longer pauses between swallows, slower sucking
- fussing *during* the feed that turns into arching, coughing or gagging (a "stop now" sign)
Signs she is still hungry: rooting, hands to mouth, sucking, stirring, fussing that builds up into a cry. (Royal Children's Hospital Melbourne, *Bottle feeding* fact sheet, checked 24 October 2026: watch for pushing the teat away with the tongue, turning the head away, and needing a break.)
Better alternatives you can start at the next feed — all routine, under 25 minutes:
- One owner per feed. Write the rule where you can see it: *"she turns away when she is full — we stop there, no top-ups."* (A script for your partner is at the end.)
- Paced bottle feeding. Hold her semi-upright — not lying flat, not slumped. Let her draw the teat in herself. One slow suck-and-swallow at a time. When she pauses, slows down or takes longer swallows: pause, hold still, let her rest, then offer again only if she reaches for it. Burp during and after.
- Stop at the first "done" cue. Do not chase the last of the bottle, and do not move to a bigger bottle or a faster teat to stop the crying — a faster flow means more air and more spit-up.
- After the feed: keep her upright for a while (NHS advises holding her upright during the feed and for as long as possible afterwards), burp, then back to sleep flat on her back. Do not raise the head of the cot.
- Crying after a feed she finished: five minutes of settling that is not food — hold her upright against you, shush, a slow walk, change of position. Then: rooting or hand to mouth → she is hungry, feed again and watch the cues again. Another vomit → stop and write it down. Never answer it with a bigger bottle.
- Fill in the feeding-and-nappy log you already have — you only need times and counts, no exact amounts: feed times, how she ended each feed, size of the spit-up, crying before and after, wet nappies. That sheet is what makes the next appointment useful.
What "normal" looks like, so you are not chasing a ghost: a small dribble of milk during or shortly after a feed, no distress, feeding well, wet nappies as usual. NHS: this is very common, usually starts before 8 weeks, usually gets better by around age 1, and usually does not need a doctor as long as the baby is happy, healthy and gaining weight. NHS also lists *crying and not settling* and *not gaining weight* among the things that do deserve a clinician's eye.
Decision tree for the next feed (screenshot this):
```
Crying after a feed
│
├─ Any red flag? ──► STOP home care → urgent / emergency help
│
├─ Did she turn away / relax / push the teat away before finishing?
│ YES ──► She had enough. Stop, no top-up, upright, burp, log it.
│ NO ──► Keep pacing; re-check at the next pause.
│
├─ Spit-up a small dribble and she is well afterwards?
│ YES ──► Common; log it and carry on.
│ NO (large volume, projectile, green, blood) ──► red flags
│
└─ Hunger cues after 5 minutes of settling?
YES ──► Feed again, watch the cues again.
```
2) Constraints and what to avoid tonight
- ✗ Force the last of the bottle, or top up after she turns away.
- ✗ Bigger bottle, faster teat, "one more feed to settle her".
- ✗ Dilute the formula below the label; no cereal or rice cereal in the bottle; no thickening powder, juice, water or herbal drops in the bottle. If her feeds need thickening, that is a conversation with her clinician — do not buy it yourself.
- ✗ Prescription reflux medicine, or any powder bought online.
- ✗ Changing her formula or any medicine on your own; leftover antibiotics; anti-diarrhoeals; supplements.
- ✗ Giving extra water or juice "because she seems thirsty" — before six months, milk is all she needs, and water is not the answer to crying.
- ✗ Raising the head of the cot; letting her sleep on her side or front.
- ✗ Withholding feeds to "reduce" the spit-up — keep her usual feeds and usual breast milk.
- ✗ Leaving her alone while she cries. Inconsolable crying is a red flag below, not a feeding problem to solve with a bigger bottle.
3) Red flags — when to stop DIY and get clinical or urgent help
Emergency now (your local emergency number, or the emergency department):
- Green vomit (dark green, bile-stained) or vomit with blood; forceful or projectile vomiting
- A swollen, hard or tender tummy
- Keeps being sick and cannot keep fluids down; refuses to feed; will not feed at all
- Floppy, limp, hard to wake, will not settle; a weak or high-pitched cry
- Fast or laboured breathing; blue lips; cold hands and feet; mottled or pale skin
- Far fewer wet nappies than usual; a deeply sunken soft spot on the head; no urine
- Temperature 38 °C or above, or a temperature that keeps changing — hot then cold. Under three months this needs same-day assessment even if she looks fine, and a low or unstable temperature can be just as serious.
- Crying in waves with her going pale and legs drawn up, or blood in the stool
Same-day clinician (book it, do not just wait):
- Not gaining weight, or losing weight
- No improvement after one to two days of the steps above
- Spitting-up or vomiting that starts for the first time after six months, or reflux still going on past age1
- Any fever, or a red or spotty rash that does not fade when you press a clear glass against it
While you wait for any of that: keep her warm, keep her upright, note the time the crying started and how many times she has vomited, and count her wet nappies. Take the log with you.
What success looks like in 24 hours
- She ends most feeds turning away or relaxed — that is the target, not a failure.
- The spit-up goes from "after every feed" to small and occasional.
- She settles and is comfortable after most feeds.
- Her wet nappies stay as usual.
- You have a log that shows what was offered versus what was left.
If tomorrow looks like tonight, take the log to her next appointment with the paediatrician or breastfeeding adviser — a weight check and one watched feed there tell far more than anything you can measure at home. If anything in the red-flag list appears, do not wait for that visit.
One thing I need to know: how old is she in weeks or months, and was she born early? Under three months changes how quickly she needs to be seen, and reflux usually settles by about age one — that tells me which part of this to sharpen for you.

Script for your partner — screenshot this:
> "Let's agree on one thing tonight: she turns away when she's full, and we stop there. If she cries after a feed, we try five minutes of holding her upright first, and only feed again if she shows hunger signs — rooting, or her hand to her mouth. The bigger bottles were making her bring up more, and that's the part we're changing. If she goes pale, gets a swollen tummy, or brings up green, we call the doctor straight away."
