My baby is 5months 5days old. From past two weeks She reduced taking feeds from 4ounces to 2ounces. When she cries I give her my milk, but she drinks only small quantity 40-60ml and starts crying biting her fingers. She also farts more. She passes stools 2-3times a day. During nights she gets up every 1 or 2 hours. When I try to feed she doesn't take and cries alot. Even mornings she is very fussy and moody. Keeps on biting her fingers. Any solution to make her drink milk and sleep well at night.
I tried all possible ways to make her feed and sleep.

I give her night body massage and shower, play lullaby, rock her, but she gets up after one hour.
