My sister (25) has a son (3) with her ex m (29). They split when nephew was 1. He found someone else and got married. Recently he has made the decision he no longer has time for my nephew and doesn't see much of them. My sister is struggling to cope and has even said that she can't cope and parent on her own to the point where she has sought advice from social services.
I'm close to my nephew and have a son of a similar age. I would love to have him live with us and keep him close to family. But I'm not sure if I can finically manage.
Any advice?
