Hi, Jaime!
I want you to enjoy your little guy while he is still clinging to you, because in a blink of an eye you are going to be screaming in fear as he takes off for Summit Plummet in Blizzard Beach! My kids used to be so happy just splashing in the kiddie pool and now I cannot keep up with them in the Water Parks.
Either Water Park will be fine for your little Mouseketeer. Both Blizzard Beach and Typhoon Lagoon have play areas for kids that are perfectly age appropriate. Small slides, shallow pools, and plenty of water fun will be waiting with whichever you choose.
Personally, my family has always enjoyed Blizzard Beach more. We love the "winter" theme, the ski lift, and the nearby Winter Summerland Mini-Golf course to top it off!
