Hi, V.,
You've received a lot of helpful responses so far, so I won't write much. I fly alone with my two babies often to meet my husband who works in other states and other countries. Needless to say, I can't carry much "fun" stuff. Sometimes, I've bought colorful little (3"x3"x1") books at my neighborhood consignment stores shortly before my trips. My kids, esp. the elder one, love these. I also bring a few colorful old magazines. My elder child, now 2 1/2, likes to look at the photos in them; my younger child, now 1 1/2, likes to tear the magazines to pieces.
Have a fun trip!
