A small amount of baby food is carried, Ella's kitchen if I remember correctly.
We flew LHR-DFW & SFO-LHR earlier in the year and knowing baby cs didn't have a seat came prepared with food and snacks for both flights, however it was made clear on both flights that we could have baby food if needed and also anything he might eat/snack on from club kitchen.
Crew were good on both flights in CW.
