My mum takes my 2 year old out on one of my work days. She goes with my auntie who also takes her 4 year old grandchild. The 4 year old has always been a bit rough with my child but put it down to normal children play. Well a while ago he started hitting, pushing, biting, pinching and pinning down my child. Obviously it is stopped by my mum quickly. I had a discussion before about it and it seemed to stop him from behaving that way for a while. Well last week my child went out with them as normal and out of nowhere the 4 year old walked up to my child (no emotion) and began to strangle my child. My mum noticed within seconds, but it concerned another women enough to run over to stop it. Well after my mum told me what happen, i said he won't be spending time with him anymore.
Well it seems to be causing problems now within the family as they seem to think i am being unreasonable and over thinking it. They dont seem concerned about his behavior. It worries me as his mother is soon to give birth. I worry how he will be towards a baby.
My child is very loving and tells me he is the one who is naughty and basically saying the child hurt him cos he was naughty which isn't true.
Am i being unreasonable?
TIA
