If he calms down n sleeps after taking feed, then it indicates he was hungry. At this age they have a small stomach. So he needs milk every 2 hours. By crying he is making you aware of his needs. Don't worry. It's normal.
Acche se peeth thapthapao. Doodh peene ke baad kandhe pe rakhkar. Colicaid uske baad agar zaroorat pade tho hi dena. 15 mins tak pehle burping karo. Yeh sabse zyaada zaroori step hota hai aur ise parents hamesha theek se nahi karte hain. Ho sakta hai ki pet me dard na bhi ho aur bachha koi aur karan se ro raha ho. Na sudhre to dikhana padega.
After giving colicaid if she still cries alot then you have to look for other reasons like insect bite, running nose, hunger cry etc. Then we can decide to give ibugesic or not. Thank you.
