My husband and I are flying from New Yor

Answer

I'll work through this systematically. Let me first load the relevant references and the trip template.

Wrote (internal file path omitted) and the deterministic checks come back **ok: true** (7 nights,1 base). Below is the skeleton plus answers to your four worries, with sources on the line they're used.

## Itinerary

**Family priority / what success looks like.** One base, slow rhythm, every day two anchors maximum, long lunch and nap built in. The trip is a success if everyone — including the baby — lands home rested and you got to be in London, not at it. A "hotel + park + café" day is a real day.

**Base.** London, 7 nights, single base (one base beats two with a 7-month-old). Stay central Zone 1–2, in a building with a lift, near a Tube station that has step-free access — that one decision removes more friction than anything else on this list.

| Day | Shape |
|---|---|
|0 Outbound | JFK with **≥3 h pre-departure** to clear TSA with bottles and ice packs at a calm pace. Overnight flight. No anchor before the airport. |
| 1 Arrive LH | Immigration → hotel drop bags → only neighbourhood walk → long nap → early dinner near the hotel. |
| 2 ecovery | One short outdoor anchor late morning → long lunch & nap → one flat, stroller-friendly loop late afternoon. |
| 3 Light | One indoor anchor (museum with pram access or a café morning) → nap → one outdoor loop → home by 18:00. |
| 4 Park half-day | Morning park (Hyde / egent's / St James's) with baby in carrier or stroller → nap → optional café. |
| 5 epeat of Day 3 | Same rhythm, different anchor. |
| 6 Slow | A stroller-friendly market or river walk; no queues; everything before 19:00. |
| 7 Buffer / pack | Morning loop near hotel; afternoon nap + pack. |
| 8 Depart | Sightseeing =0; hotel → LH with **≥3 h** buffer; overnight back to JFK. |

**Degradation day (legal to use).** ain, a meltdown, a nap that won't end — any day becomes a hotel + covered market + café day. That's not failure; that's the whole point of having a single base. Indoor backup already named on Day 3.

## Booking table

| # | Item | Notes |
|---|---|---|
| 1 | Bassinet seat confirmed on **both** legs, in writing | equest ≠ assignment. Confirm in Manage Booking ≥72 h before departure; bassinet rows are first-come on some carriers and not all bulkhead seats qualify. |
| 2 | Lap-infant vs own-seat decision per leg | Below 2 years old you can fly lap-infant. With overnight + bassinet +7 months, a separate seat for baby is often cheaper than you think and unlocks a CAES harness or your own car seat. |
| 3 | Hotel with lift, near step-free Tube | One-line email to the hotel asking "do you have a lift, and is the nearest Tube station step-free from street to platform?" — that email prevents most of the week. |
| 4 | Stroller gate-check vs cabin decision | Most carriers gate-check a folded stroller for free. Decide now so you don't choose at the jetbridge with a baby in arms. |
| 5 | UK plug adapter (Type G) × 2 | One for you, one for the bottle warmer. Don't count on the hotel having spares. |
| 6 | Travel insurance that covers a 7-month-old | Specifically check that infant medical cover isn't a rider that excludes pre-existing care. |
| 7 | A paediatrician visit in the week before | Not booking travel medicine — just a routine clearance and an ear check (see anxiety #2). |

I don't book anything for you. These are the seven things that, once they're decided, the rest of the week falls into place around.

## Your four worries, with sources

**1. Turbulence and the bassinet.** On BA's family seating page, the rule is that an adult holds the infant securely on the lap during take-off, turbulence and landing — the bassinet is for the cruise phase, not the bumpy phases. So when the seatbelt sign goes on, baby comes out of the bassinet and onto your chest with the loop belt extension; when it goes off, baby goes back in.

**2. Ear pressure during descent.** The CDC Yellow Book is explicit: pressure in the middle ear is equalised by swallowing or chewing, so infants should nurse or suck on a bottle, and older children can try gum. For a 7-month-old, that means a feed (breast or bottle) or a pacifier from before descent starts through landing. If your baby has had an ear infection or ear surgery in the two weeks before the flight, ask the paediatrician whether to fly — that's a separate call.

**3. Breastmilk, formula and ice packs through JFK.** TSA's own page: formula and breast milk **over 3.4 oz / 100 ml are allowed in carry-on** (the normal liquids rule does not apply to them). Ice packs, gel packs and freezer packs used to keep them cold are allowed in carry-on, even if partially melted. Tell the TSA officer at the start of screening that you're carrying them; they will be screened separately and you can ask for an alternative to x-ray. There is no fixed quantity limit — bring what you need for the trip.

**4. ealistic London pacing with a 7-month-old.** Treat the week as one anchor in the morning, one anchor after the nap, and home by early evening. Walks beat museums; parks beat queues; a covered market + café beats any itinerary. With a baby this age, the trip is genuinely better if you plan less — every "should we do X?" can be answered by "is it before 19:00, near the hotel, and would baby survive a20-minute walk?" Step-free Tube stations are the single biggest unlock for getting out of the hotel with a stroller (the TfL step-free map is the page you'll actually use all week). Day 1 after landing is hotel-neighbourhood-only; that's the day you earn the rest of the week.

## Two small things you didn't ask but matter

- **UK entry for US passports.** US passport holders do not need a visa for tourist stays under 6 months; passport must be valid for the entire stay. Confirm both on the day you travel.

- **Frozen breast milk in hand luggage into the UK is not allowed** (it is allowed in hold luggage). If you're bringing frozen milk for use during the week, it goes in checked baggage or you carry liquid/refrigerated milk in hand luggage.

## Two gaps I haven't asked about (max two)

1. **Exact dates and which flight (overnight JFK→LH or daytime).** A daytime arrival makes Day 1 salvageable; an overnight arrival makes Day 1 just sleep. This shifts the day shapes above, not the base.
2. **Lap-infant vs own seat on each leg.** This decides whether you actually get the bassinet, and how the whole flight physically goes. You don't have to decide now — you do have to decide before booking.
