We are flying London - New York for a relocation. My husbands company have booked us business class but this means all three kids are in their own seats (with their own sliding doors). Our youngest has just turned 2 so requires her own seat, and will have to sit by herself at take off and landing and whenever the seatbelt signs are on. Does anyone have any tips for how to manage this, would it be best to use a car seat or just hope that she will sleep when the seat is flattened into a bed? The flight is at 6pm so is close to bed time… She’s never flown on a plane before and the older children have only been on economy family holiday flights before (but I think they will be fine).
