With a seven month old on a plane, it can be pretty hard to feed the baby without making a mess, but we have a long flight ahead of us in coach as part of holiday travels. He is old enough to be wishing to feed himself, can do so with puffs and baby crackers and the like, but still eats pretty soft and juicy kinds of things otherwise, so he often winds up fairly sticky (and so do those that are nearby).
Any suggestions?
