I just took my 11 month old for the first time. We have season passes and go once a week in the summer. The water attractions are good for little ones. There's a big wade pool to sit in and splash and she loved Count's Castle. We just walked around at the bottom and the water dripping down was nice. Also the carousel, we sat on the bench together. The lazy river is nice too. My dd sat on my lap while we went around. Just be the look out because there are water falls that make you get WET. On the rides you will have to take turns, but if you go on a nice day it won't be that bad. One can stay at the water with the baby and the other person can go on the rides and slides with your son. Have fun!
