Screaming from the kids bedroom turned out to be my 6 year old trying to stop his 3 year old brother from smashing with a toy hammer a Lego robot the 6 year old had built. I stopped the 3 year old as calmly as I could, removing the hammer and telling him not to break his brother's Lego build especially when asked to stop. The 3 year old started screaming and an hour later has not stopped.

Both my husband and I have explained to him several times why his behaviour was unacceptable and the he's upset his brother and needs to apologise. We've said he can say sorry, offer a cuddle or draw a picture to apologise but he just keeps screaming at us. He wants me to cuddle him but I'm worried he'll then think he's gotten away with his bad behaviour.

We have 3 kids and since our daughter was born I have struggled to control our 3 year old partly because he is a bit more headstrong and wild and partly because I haven't coped will mentally since having our 3rd.

Should we keep trying for the apology or just let it go? Any advice on dealing with this in the future?
