My 2 yr old son (11 kg wt) is having severe constipation since last 3 months. Only able to pass motion with suppository every 5, 6 days. He is very fussy about taking medicines, throws up whatever we give, giving him Laxitol syrup 10 ml twice daily mixing in bottle milk ( so he is not able to find out) for last one week but no help. Tried giving Cremaffin, he doesnt take this medicine. Pls help and prescribe medicine. And what could be the cause of this chronic condtipation. We give him fruits, veg, enough water also.
