This might be a little long and I definitely don't want it to sound like I'm bitching but genuinely curious.
We are all currently away on holiday and are enjoying the pool. My 3 yo has just started lessons, I didn't have the time to do mother and baby (full time work) so that was the only choice really.
SIL only works part time and was able to do mother and baby from 3 months and my nephew is a great little swimmer! I'm not taking that away from him, he is really good.
Anyway, we sit on the step bit of the pool and my son has a float on because he obviously can't swim and kind of just potters around the the shallow end. Nephew frequently swims out to the deep end (he's only 3!) and goes underwater a lot. My heart sinks every time and I'm constantly having to look at him, while she is there looking at me talking and not keeping an eye. I said to her that I can't focus on the convo because I'm keeping an eye on DNephew, she says that I don't need to keep a solid eye on him as he's a strong swimmer. Yes, he is a good swimmer, but really 'strong' he's 3, so definitely not a strong swimmer. He always comes up and is fine but there's 4 more days of this holiday and it's so blooming stressful, I feel like I constantly have to watch as she casually picks at her nails, talks to whoever. Yes, she is always in the pool but at the shallow end and he kind of drifts off a bit and does his own thing.
AIBU to think this isn't responsible?
