DS has never been taken to an indoor swimming pool by either me or DP.
I really hate swimming pools, I hate the smell, feel and taste of chorine, the heat, the echoey noise, the changing rooms....everything.
Once he has had his bone surgery we will send him for a proper course of swimmimg lessons as I think the ability to swim is vital. But hopefully by then he will be able to go without me having to go in with him.
He has been in the Lido a few times, and in the sea, lots, and a couple of times with friends and relatives - but 'in passing' not because we have made any effort to make sure that he does.
He's done plenty of other enjoyable 'extending' and constructive activities.
Doesn't bother me if anyone has the energy to feel judgemental about it, but not sure why anyone would.
