Jackson is obsessed. He will play in the water even when the weather is in the 50s. But he will always find a puddle or some kind of body of water to lay in. He does not like the bath tho- the one body of water he does not like LOL.
It took him a whole summer before his began diving in though. His first summer he did not dive or jump in. Second summer he began jumping onto the raft and then getting in the water that way. He LOVES it and lives for the pool in the summer. I have always encouraged him to try new things without forcing it, etc, so I think he just learned how much he enjoys getting cooled off in the summer. He also began copying all the kids who jump in.
We just opened our pool 2 weeks ago. This is typically how he spends his days:
