I'm not sure the best way to tell you this because I don't want to rain on your parade, but please be careful, especially with your little one. Adult dolphins slap their tails when they are upset and want to tell others to stay away. Especially protective moms with babies. They're 500 pound wild animals that play by biting each other. Bottlenose dolphins ("Flipper") have especially been shown to be aggressive, killing each other, other dolphin species, and even porpoises. Contrary to what those bastard swim-with-wild-dolphins tour operators would want you to believe, dolphins have been documented killing and seriously hurting people who have tried interacting with them in the wild. Which is half of the reason why it's illegal to approach a wild dolphin in the U.S. (You can read all of the government's reasons here: http://www.nmfs.noaa.gov/pr/education/protectdolphins.htm ) It's kind of like assuming it's safe to play with a pack of wild dogs just because someone's domesticated dog is nice.
That being said, I'm so glad you had such positive experiences seeing dolphins! Especially the rare chance to see babies! I agree about how inspiring it is to see one out in the wild. They are such beautiful, fascinating creatures! I know I feel blessed everytime I see a wild one.
