have beeen very close/best friends with my mate since we were young.we are now both 32.she has a 22 month old ds and an adorable 11 week old.the problem is that for the last couple of weeks her 22 month old son keeps hitting my 3 year old constantly,at first we just dissmissed it,appart from she did tell him no,thats naughty,you must not hit ect but it is becoming more and more.my daughter does not hit him back,but she is very verbal and she says no,tells me and his mum ect.but i have to be honest it is starting to get to me.ive even stopped seeing them as much because i dont want his behaviour rubbing off on my daughter and i certainly do not want her being hit.im afraid that it is starting to effect our friendship,my friend does tell him off but he smack her in her face and even tries to headbutt her!we take the children to soft play together and hes hitting any/all of the children there also.my friend left early today because she couldnt take her eyes off him,he was hitting all the time.just going up to any child and lashing out for no apparent reason.i feel really bad for her she is sooooo stressed and she has only just had baby number 2-who is 11wks old. why is he doing this?
