I'm thinking of deciding to throw my hydrophobic son in the outdoor pool.
Why would you want to scare him like that?
I don't have any other soloutions.
You may be creating more problems than you think by doing that. It's wrong to just up and throw your son in the pool. He'll eventually come around.
He won't go anywhere near pools and I think this will fix the problem.
No it won't. He will resent you and will be even more afraid of pools.
