Toh aap formula feed bhi de sakte he

Agreed with both comments

But mother ko milk jyada nahi hota kyuki half hour tak bachhe ko feed karwati hai phir bhi bacche ka pet nahi bharta

This means baby is not taking good feeding.. advice mother to feed the baby every 2nd hourly and on demand.. and it is mandatory to check the pee count of baby- atleast 6 to 7 times a day,this recognises the breast milk secretion.. if the breast milk is not enough switch formula feed under ur doctor guidance..

Yes it's good. Babies weight initially reduce as the excess water accumulated when they were in the womb gets dried. They will gradually gain weight after one month. Keep the baby on exclusive breastfeeding until six months
