The situation might not be as it seems, my youngest brother almost drowned as a child and from an outside perspective my mother would have look incompetent.
We were on holiday at a Haven holiday came and my middle brother and I were on and off the large twisty water slide. My youngest brother (age 3) begged to go on.
Knowing he was under both the age and height restriction and that he would simply be send away when he got to the top of the steps as lifeguards had been doing all day to other children my mother took off his arm bands and sent him up with us to stop him going on about it.
My other brother and I went on first, my youngest brother was behind us. My mother stood at the bottom of the stairs waiting for him and watching him at the top of the slide. She couldn't see him past a certain point though because he was shorter than the side barriers.
My middle brother and I came down and swam to the side, my mother was vaguely aware of a lifeguard diving in. It was only when he shouted 'whose baby is this?' while holding my brother over his head that she realised he had been allowed down the slide and the lifeguard had dived in when he didn't come up.
Weirdly she doesn't actually remember most of this, she only remembers the near drowning, she doesn't remember why she let him on the slide that was too old for him, why she didn't see him come down and why she was so far away from him when he was in the water.
I think she is a bit traumatised, I filled her in with my own memories of the even recently when we were discussing water safety for my own three year old. All she remembers was she took her eyes off him and he nearly drowned.
She completely blames herself whereas I think she is only partially responsible, I should have insisted he went first so I knew they were sending him back down the stairs (I was eight so old enough to keep an eye out for him) and the life guard in charge of the slide obviously didn't follow the height restriction, the age restriction or the rule about asking kids if they could swim before letting them down.
Not everything is always as it seems, I am glad the child was ok. It must have been shocking to see.
