I am prepared to be told that this is none of my business and that IABU but I am coNcerned and I don't know what else to do. I don't have any children of my own so I know I may be wrong. My DN is 3.5 and ever since he's come off breast milk, he hasn't eaten a single solid food apart from weetabix, chocolate biscuits, crisps and bananas. SIL will not give him anything else, she refuses to cook or even buy him ready meals or chicken nuggets or anything else that is solid. He's never had potatoes, rice, vegetables or anything like that. Not even pasta. I am obviously concerned about his well-being and if he's getting the nutrition he needs as he doesn't have any supplements or vitamins either but every time I mention it, she says 'he won't eat it so there's no point' and changes the subject. He now got to the stage where he just won't accept any new foods and now that he started at nursery, they noticed it and referred DN and SIL to a specialist or nutritionist which she refuses to go to. She says that he's just not ready for any other foods yet and they don't need help. She sends him to his dad's every weekend where they smoke inside the flat and they sit him in front of the TV for the whole weekend. He always comes back stinking of cigarettes when we pick him up. Again, she says that he needs to see his dad and she won't get in between them and their relationship. I feel really sad and feel that it's unfair on my nephew but what do I know.
