I have a 5 Yo boy and a 6 month old boy. My eldest has no interest in his younger brother at all.
When he was first born there were signs of aggression, which we addressed and he is much better now. However, the lack of interest does cause myself and Fiance concern. He would much rather play by himself in his room than be included in playtime with us and baby. He then says he feels lonely in his room. We try and include him as much as possible but he chooses not to participate.
Has anyone else had similar experiences? My Fiance and myself both have siblings and are close to them all, so we worry that when they are older they will have no bond or friendship.
