When I took my DD (young 3) in September, whenever I would drop her off, the first thing they would have me do was take her to the bathroom & wash hands afterwards (anything to try to keep the Norwalk virus away). As small/low as the sinks were, some were easier to reach than others for little ones. My plan was to come to the club every few hours & take her to the bathroom so there wouldn't be accidents but she didn't want to stay that long. I did see potty breaks at the activity changes (all the kids lined up waiting for others to finish), but don't know if that is normal or not. Plan on checking with him occasionally.
