Hi Judy,
I am sorry i missed that thread some how,although i don't have a child with thal minor but i know toddlers can be difficult sometime thal or not,my son also is a restless sleeper,kicking,grinding teeth and screaming goes on often,for grinding teeth i was told that it can be due to stomach worms,we did give him treatment for that and teeth grinding was reduced by 50%,though children with stomach worm tend to eat more and not gain weight,but still you can check your son for it.Because i remember my husband's nephew who also is a thal minor,was a really bad eater and then he was treated for stomach worms and the issue got a little better,although he still is a picky eater and i often watch his mother struggling with him to eat now when he is old enough to eat by himself.
Giving bath at night time might also help,and i found this with my niece that massaging olive oil in scalp and on the bridge of nose also helped,your son is 3 years old otherwise i'd advise you to massage his whole body,as we do with younger kids here,but i know how hard it is for a toddler to sit still or lie still for a massage.Warm milk at night time is also supposed to help,and put a little bit of turmeric in it,( These are all our local home remedies
)
As for not eating,some kids are that way ,small, frequent and colorful meals might help,or engaging him in any kind of activity he likes while eating,like cartoons or building toys.
Hope this helps
