constipated baby??

i think my DS is constipated  

he has seriously pooped once in the past 24 hrs...
he is 11weeks old.
he still farts every so often, but no poo  

what do i do?

Is he breast or bottle fed? Breastfed babies it's normal not to poop that often. And if it's only been 24 hours I wouldn't worry yet.

How old is he?
BF or FF?

I know for EBF babies they can poop up to 10 times a day or once every 10 days and still be considered normal! Try tummy massage, and doing "bicycle" legs if he goes 24 hrs without poop.

I am not sure about FF though, there are probably different guidelines.
