I agree with dawnM, just to add- he might have stomach colics, which are typical for children if there is problem with food they it- if you are giving him some formula which his stomach cannot tolerate, (babies often cannot tolerate cow´s milk in formula because of lactose intolerance) - he might be in pain. If you are breastfeeding him, you might eat some food (like onions, garlic, spices) which he can feel in your milk - so the result is pain in stomach again. When he is completely exhausted from crying, THIRST and HUNGER he falls asleep.
He needs to eat - if his problem is persisting longer then day or two, he might dehydrate! So take him to the doctor to check him, but consider changing the food he eats - to solve his problem permanently.
Take your 4 month old to the doctor, this does not sound normal! A baby eats about every three hours at that age, the sleeping in the day, is not abnormal, but along ith not eating that sounds like a problem. Good luck.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
