Good Morning, my 2years baby girl is facing constipation problem last 2 days (didn't pass the motion ). Yesterday, we visited pediatric and he suggested "duphalac i.e. lactulise solution usp" with dosage of 5ml. we gave 5ml dosage last night and today morning but still she is facing constipation problem. She is crying while trying to pass the motion. She didn't have constipation problem before. can someone please help on this? is this serious? baby weight: 10 kg 22 months note: she usually pass the motion 2 times in a day.
