I hope someone comes along who can help. I haven't visited with an infant.
Two adults and 2.5 year old can fit on most rides .. it's the 6mo old that is tripping me up.
There are two guns on buzz & TSM...but I'm pretty sure an adult would need to help the 2.5 year old, so one car still works.
Nemo, Under the Sea, Pirates, the land, Magic Carpets, dumbo, triceratops, Safari, Navi, Carousel, SMall World, Pooh, tea cups (can a 6 mo old do this?) should be fine. For some reason the safety bar on HM & wearing the 6 month old bothers me...not sure why...
MMRR is fine, jungle cruise works, Peoplemover is okay. Spaceship earth too.
