Took dd to a parent and toddler swimming session today at the local pool. I was sat on the steps while dd sat next to me splashing in the water and a little boy probably around the same age as dd (18 months) was coming towards me and kept dipping under the water, gasping for air. His mum wasn't far behind him but kept saying things like 'go on, don't be a wimp'. He started to cry and then completely went under when he was practically in front of me so I lifted him up without thinking. His mum then snapped at me and said he's getting used to being under water, don't touch him. Was I being unreasonable to lift the child out of the water? He was under for a few seconds trying to scramble to the top.
