Constipation is quite common in babys less than 1yrs of age No need to worry for that Give tummy times  frequently  in a day time Feed ur baby as per demand Burp properly at least 10 min or till baby take 4 burp Keep a watch on urine output Baby should pass minimum urine 6-8 times per day If baby is feeling discomfort and crying exessively then Need to do rectal stimulation, apply some drops of oil over motion area It will help If doesn't work then Need rectal enema for which u need to visit ur nearest pediatrician once

I would like to know some things. Are u breastfeeding or is the baby on formula feeds? Are u giving the baby anything else except your milk?
