Genuinely interested if I'm just being precious. My son is 4, it's obvious he can swim, so I didn't have the added need to be annoyed at the idea he could have struggled in the water. There was a man with his 3 daughters and they were jumping in, sometimes the dad was throwing them in. My DS was then jumping in, he stopped to look at the girls being thrown in, the man said would he like a go, DS looked at me and I said no, he's fine but thanks anyway. It was left. He kept jumping in and the girls kept jumping/being thrown in... Then all of a sudden he grabbed my son and threw him in laughed and said 'gotch ya'. DS laughed and found it fun, but I did already say no... AIBU to think you don't do that?
