Here's how that worked out for us:
Could he possibly sit any further away from the class? He was as far up in the corner of the pool as possible. He alternated between crying and sulking in the corner and doing his best to ignore the class and the teacher. Fortunately Christian had a better time of it.
After class we asked Jordan why he cried so much since he's a big boy now. He said "I don't know". We reminded him how much he loves swimming (he actually does) and how nice the teacher is. We told him no more crying in swim class OK? and he said he wouldn't cry any more (sure bob, we'll see about that). The following week, we braced ourselves for a repeat performance.
And we got this:
We got lots of smiles and lots of swimming. Who knew? He was telling the truth! Ever since then, he loves the class and his teacher. In fact, he loves it so much I have to keep an eagle eye on him because he just throws himself all over the pool as if he were a champion swimmer.
