I always take empty bottles and cartons of milk if I'm going to feed ds2 out and about. I've been putting them in an Avent bottle carrier thingy, but the leftover milk in the bottle always leeks out all over the bag and it is a PITA to clean and dry afterwards.
Has anyone spotted anything specifically to fit Dr Brown's bottles (ideally 2 of them at a time). Off on holiday in a couple of weeks and don't really want leaking milk all over the pushchair, car etc.
