At DD1's swimming lesson today, a man got into the public bit of the pool with a 7 week old baby in just a swim nappy. The pool is at a private gym and quite a pleasant temperature for adults but too cold for an almost naked baby. I take DD2, 8mo, swimming there with a swim nappy, swim pants and a wet suit. (Possibly overkill, but she seems quite happy).
I was really unsure whether to say anything and asked another mum who agreed with me but also didn't say anything. They stayed in for about 10 minutes and then I saw them again in the family changing room. At this point I mentioned to the man that you can buy wetsuits for babies as it can be quite cold in the pool. He said he didn't know and asked where he could get one.
Should I have said something earlier? Or nothing at all? The baby didn't seem unhappy and luckily the man took my comments as well meaning advice rather than criticism. More a WWYD than AIBU?
