Since 2 days my kid is fussy. She is taking feed for 5-7 minutes and not burping. Because of smaller feed she felt hungry again and again. Also, it seem she is gassy and passed lesser stool yesterday.

She give expression as if something is bothering her which she want to take out but unable to.

I am so worried. What to do? How to ensure that she is able to digest the feed given it her.
