BM and I are expecting a child of our own in May. SS and BM moved in this month to start to prepare for new arrival. I have known SS since he was 1 and have always gotten along with him. He is two now. But since he has moved in, there have been several occasions where he has cried when i have come home and shouted "NO!" when i come near him. BM tells me not to take it personally, but i cant help but cry when my son treats me like that. Has this happened to any of you? Any advice?
