DS1 is 4 in May and has a bout of sickness once or twice a month lasts or no longer than 12 hours. His appetite is very poor and has not gained any weight at all in over a year. His skin is very dry (he does drink plenty of fluids) and has to take laxatives sometimes as he gets constipated. My dad has Chrons and DH has Diverticulitis which has resulted in a stoma, reversal and a Hemicoloectomy where he's had most of his bowel removed. I don't know if this is related but his behaviour has changed and gets very frustrated very easy and is always complaining of being tired, feeling sick and has stomach aches. Going to see the Paed in March about it. Any help would be greatly appreciated.
