my poor little baby boy has been crying for the past 4 hours because he cant poop. i feel so bad

I had to massage my baby's tummy for a good hour or so and move his legs in a bike motion. He passed it the next morning

How old is he? if he is old enough you can put kro syrup (spelling) I'm his bottle and it will help him go.

Have you tried rectal stimulation. Or tried giving the baby some apple juice only 1oz
