Good day, kindly advise if it is goo to give a 3 weeks old baby a milk magnesia or gripewater for constipation. he has 3 to 4 days without pooping. and his stomach is is grinding and he cries alot when that happens.

I wouldn't: A 3 wk old infant can go a week between poops if breast fed or go a little every feed. If soft when they go it is normal. Their stomach often grinds and they tighten it to help push digestion. It is art of their normal. If the stools are truly hard I use an ounce of full strength prune juice 1-3X/d to loosen them. It works in 2-3 days.

Exam/but may be norm: The pattern may be normal for this age, no treatment needed. The baby should be examined to ensure that there is no anatomic reason for these symptoms.
