Hi!
Congratulations! You are going to have two pretty close together!
There is no reason to avoid the carousel, or for that fact any other non-contact ride. The only risk would be associated with any ride on which you might have trauma to the abdomen. So I would avoid the bumper cars, etc for example. But if you wanted to ride the kiddy train or something like that--indulge! Have fun with your daughter while its just you two girls!
Good luck!

Yeah, as long as it is a kid friendly ride, you should be fine.
