We took my son when he was six months, and were surprised at how many we could take him on. Pretty much anything without a height restriction. Use your discretion, though. If the baby dislikes loud noises, maybe don't take him on pirates where an entire boat will have to listen to a screaming infant, but if he does fine and sleeps through most noises (like ours did) go for it! Also, use the rider switch!!!! Coolest thing ever. - LittleAprilShowers  471.0 #257 2:42PM

Baby can go on anything that doesn't have a height requirement. Hope you all have fun! - preggoprincess  183.1 #1824 2:29PM

He can go on anything without a height limit. Unless he's really tall for his age. Then he can go on anything - Mouse4life  1040.7 #82 2:31PM

You can take the baby on pretty much all the slow rides. All the rides in Fantasyland, plus, Haunted Mansion, Pirates, it's a small world, Winnie the Pooh, rides like that. Also, take advantage of the mother/baby center on Main Street, by the First Aid station. - kss4tink  216.8 #1393 2:31PM

Pirates...after the two drops it's smooth boat sailing...very peaceful - Disneyrockstar  119.3 #2742 2:34PM

Thank you so much for the replies everyone! I didn't realize he would be able to ride so many attractions. I assume she will be able to hold him in her lap while she rides? (Since he obviously can't sit up on his own) - Fruitbythefoot  33.3 #4230 2:51PM

If you do teacups do it really slowly! Almost all fantasyland rides work! Just be careful on the scarier ones like snow white - bunnyforce5  5.1 #10321 3:07PM
