When my daughter was born she poo'd 3 times in the first 12hrs. And the consistent min twice a day poos came until the end of March when she was about 13wks. Now she poos on average every 3 days.

She's still gaining weight and does not seem to be in pain, but she is quite gassy all the time, even though she's eating every 2.5hrs when awake and every 5hrs during the night.

Is this normal at 3-4months? Should I be worried about her not pooping everyday?
