Background info
A very good friend of mine has a 5 year old boy who is good friends with my 4 year old daughter. I help them out once a week by picking the boy up from school.
Incident 1
Last week there was an incident where my 4 year old was spinning around the room and she bashed into him by mistake. He reacted by punching her in the stomach. She was devastated and cried a lot as it really hurt. I told him "We don't punch in this house" and asked why he did it. He said she hurt him first and his dad had told him that if someone hits you, you hit them back. I explained that she did it by mistake so it's still not ok. (I actually don't agree with hitting someone back if they hit you first but it's not my place to say this to him as I'm not his parent). I let the mum know when she picked him up and no more was said.
Incident 2
A week later, I pick him up from school again and his teacher said he'd hit someone at lunchtime. I said I'd let the parents know.
When we got to mine after school, I reminded him that we use "gentle hands" in this house.
Mum comes over 2 hours later, I tell her about the school incident and she pulls him aside for a lengthy discussion.
Incident 3
20 minutes later, they're playing with some cars outside and he snatches one off her. She shouts at him quite loudly to give it back and he punches her again. Mum then makes him say sorry and takes him home.
Help!
I don't blame him - Maybe he's not enjoying his new class in school or he's struggling in some other way. It's not my place to interfere with that side of things and I'm sure my friend will work out why he's lashing out all of a sudden and will work with him to manage it.
The reason I'm posting is, it's my daughters party this weekend and we've hired a hall and bouncy castle. His mum and dad are working so I said I'd look after him and take him to the party. After the party, he's coming to ours for a sleepover. I am so worried he'll hit either my daughter or another child at the party. I'm looking for ideas to prevent it - especially as his parents won't actually be there!
Has anyone experienced a child lashing out physically before and if so, what would you do? Shall I follow him around for the whole time? Should I bring something else for him to hit if he gets angry? I can't really uninvite him. We agreed to me looking after him way before this behaviour started...
I'm gutted as I feel like instead of running around with my daughter enjoying, I'm going to be following her friend around making sure he's not hitting anyone :(
Thanks for any tips / advice. I'm curious to know everyone's opinions.
