Ok so after all this discussion I have a question and some advice to ask..
My son is 13months and really small for age, weighing only 8.5kg now. He is forever (or so it seems) cutting teeth and gets a cold along with it. The last month he has had a cold, cut molars and got upper respiratory infection. Each time one of these occur he stops eating! Its so traumatic for both of us cause I feel there is no way he is going to grow while its going on like this!! If he was a normal weight I wouldnt have been so bothered about it.. Now eveyone tells me that as long as he still drinks fluids he will be fine, but he doesnt (and never have) drink the amount of milk he should in a day and drinks even less when he feels down.
Ok so now that you have the history.. he was just better for 2wks now and started to eat again when this morning suddenly a cough again and green runny nose??? He was fine yesterday

And already he didnt eat breakfust or lunch! So what can I then give him to stop this damn cold so it doesnt get any worse????? arrrgghhhhh!!!!
