We are flying to Europe in a few weeks and LO is on purees now. We were thinking of bringing puree pouches for the plane ride.

Should we try to bring enough for the entire trip? We'll be gone for 3 weeks. Or should we try to buy things there (we'll be in England and Romania)?

Will the puree pouches burst if I put them in my checked baggage? I'm worried about the air pressure changes on them.
