So the other day I picked my 3 year old son up from nursery and as we were leaving the facility lots of children noticed an attractive toy with a button just outside of the nursery. The children were running up to it as they were leaving, all wanting to press/hit the button. My son tried to run up to it, but as the situation was chaotic, I stopped him and told him to wait his turn. I made him wait for several minutes, standing with him about 6 feet away from the toy, while talking to him about why we were waiting. When things calmed down, there was no one near the toy, and most of the other children nearby had left, I told him it was his turn and to walk nicely and go push the button. He walked over to finally push it and a little girl ran over from about 15 feet away, sprinting from behind him, and hit the button (violently with a big slap) before he did, right in front of him. Her mum was calling out "go go press the button go go go!" He was stunned, then clearly frustrated, and ran up and hit the button really hard just after she did while she was still standing there. The mum said to him, "Say you are sorry!" I asked what happened, and she said he had hit the little girl. That had not been clear from my vantage point, but I made him say sorry and also apologised that it had apparently happened. The little girl looked upset and cried so I assumed he must have hit her as he hit the button and of course felt bad. The next day the mum came up to me and said that when my son hit her daughter it had left a mark, and that she was upset but she wasn't going to report it, but wanted me to know because any parent should want to know. I asked if she was sure a mark was left from the button incident and not something else, and she said yes it was definitely that incident. I again told her I was very sorry about the hitting and surprised and sad that it had left a mark and said we are always working on discipline and of course will talk to him about it and keep working on discipline and teaching him how to manage emotions/frustrations. I asked if the mark was still there and she did not give a clear answer. I did feel that she was very angry and emotional and that she was indirectly threatening to report my son by saying "don't worry, I'm not going to report it". Am I being unreasonable to think that mentioning the potential to "report it" was an overreaction? I can understand feeling angry as a parent if another child hits, esp if it actually leaves a mark, but at the same time, it happens quite a bit in nursery aged settings, including happening to my child at the hands of others. The little girl in this incident seemed to be trying to beat my son to the button and hit it very aggressively when she did right in front of his face it was not a calm or friendly approach on her part at all and while it's no excuse to hit, her behaviour did not help keep the situation friendly. Another child once bit my son so that his skin was broken and the mark that incident left lasted for several months. I was naturally angry about it, but did not threaten the parents and knew the nursery was on top of it and monitoring the biting child. I came away from this interaction thinking "what does this mother want from me in this?" She already had an apology on the day of the incident. Of course I work hard to train my child not to hit when situations upset or frustrate him, and I will keep doing so. In nursery the staff are all on top of making sure children learn proper behaviour. So why would this woman come up and talk about "reporting" the incident, or make it sound like she was being lenient and kind to not report it?
