My SS has a brother from his mom that is a year older then my son. I do not interact with her son ever like a normal situation. BM will aww and such when BS gives SS a huge and such. I don't so the same ever. But lately when BS does something SS says "my brother can do that" I keep telling him to stop they are very different ages. I want to freak and say "your brother is behind and BS is a head it is sad that they are even close developmentally" I this morning I realized SS was doing this on purpose to piss me off. I just don't want BS to ever feel like he has compared to spawn of BM. I might lose it tonight on SS if he does it one more time. Any Advice?
