I have my oldest grandson and my sister has my middle grandson. The reason being due to severe neglect, physical, emotional and verbal abuse. The grandson my sister has custody of is a bedwetter. At least four times a week, sometimes more. He used to horde food and still has a fear of not having enough food to the point he will get nervous if he thinks there isn't going to be enough for him to have two plates full of food at dinner. He eats huge amounts of food and has started gaining weight. He is six and wears a size 10 in pants. My sister doesn't want to tell him he can't have as much because he was starved while with his parents. He is also very shy and untrusting of people he doesn't know. He has recently started vomiting when he gets nervous, for example, we signed up both boys for swimming lessons and he became so nervous he vomited. His aunt took him to a small play park for kids and when she asked him if he would like to get on a very small ride made for children even younger than him, he vomited. He gets upset very easy if he thinks he has to do anything new. He can become very angry and agitated. On occasion, when he poops, he will play in it and then says he doesn't know why he does it. He has been living away from his parents for over two years and has had the food issue and bedwetting, but all the other things going on with him have just recently started. He has been to a psychologist, but it didn't seem to do anything for him, according to my sister. I am very worried about him. I have read sexual abuse can be a factor when children binge and find security in food. We are not aware he went through that type of abuse, however. I would appreciate any input on this. Thank you.
