So I was at the swimming pool this afternoon with my DTs (3.2) for their swimming lesson. Afterwards, we all had a bit of a swim/play together, then got out for a shower and to get changed. Just after we got out of the shower, the other two kids from the swimming lesson came through, with their mums, both of whom had a small (ish) baby. They all disappeared into the shower, and then the two mums re-appeared with the babies, leaving the toddlers (they're the same age as my DTs) in the showers on their own. I was quite shocked. The showers are not in view at all although we could hear the kids (screeeeeaming and running around) and the temperature gauge is at waist height on an average adult. Both mums got the babies and themselves changed with their toddlers out of sight in the showers the whole time. Obviously I wasn't timing it, but I got myself and my girls changed and blow-dried their hair before leaving the changing room, and the other two kids still hadn't emerged. I don't know either mum well enough to comment, but I thought that was a tad dangerous. AIBU?
