SO SORRY IF THIS UPSETS ANYONE BUT I NEED SOME HELP & DONT KNOW WHERE ELSE TO TURN
Hi girls im not sure where this is ment to be but need some help
My brother in laws brother has a 2 yr old son and a 6 month old son and my sister visits now and again and evrytime she comes back and tells me that this man and his g/f are misstreatin there boys she says they both smell and look unclean and the younger baby isnt putting weight on and looks tiny ( i know weights and things in babys differ) she also said that the younger babys chest rattles as they smoke around him (Heavily) i might sound like a hypocrite as i am a smoker and have cut down alot since falling pregnant.
She also said they leave him in a room alone for most the day and dont bother with him & his dad says he hates him and wishes he was never born & if they where round him for a few hours it would put them off ever having kids
She also said to me about a yr ago quite insensitively only a few months after we lost enzo that the dad had said when the eldest was younger " wouldnt it be funny if we went to him one morning and he was dead in his bed" WTF!!!!!

funny i felt like goin round and knocking the living daylights out of them they made me so angry
im not sure whether to dig further and try and get some info on where they live etc and contact child protection/social services im torn as i dont think my siister would lie but if i dont do something and something awful happens i would never forgive myself
Please help me !!!! SORRY ITS SO LONG
