Normal po bang ire ng ire yung 4 months old kahit hindi natatae?

Ay, pwede yan ma-stress ang baby kung constipated siya, lalo na kung days na hindi natatae! One of my mum friends' baby din ganyan at grumpy na grumpy, parang uncomfortable lang talaga. Usually kahit konti lang poop, kung soft pa, okay pa rin, pero kung mahaba na talaga walang output, better to check with your doctor na para sure, especially sa 4 months pa lang kasi baka kailangan ng dietary adjustment depende sa formula o breastmilk balance. Paano siya kumakain naman ngayon, exclusive formula or breastfed?
