That thought crossed our mind as well
But I'm a terrible actress and wouldn't want anyone to think I was mocking people with true mental illness by pretending a doll was my child and then laughing about it. As it is I'm probably going to bring the "Boppy pillow" on as a "flight pillow" and get a bunch of weird looks - that thing is HUGE and very clearly for babies. Oh well!
Should we box everything into the car seat box? Or are you suggesting a different bag? I know I've read other posts about people checking in cardboard boxes with mixed results so I wasn't sure if that would be advisable for this situation. How would they "tag" a box like that?
