How is it given according to weight? Please advise..

Hi there is no such things, mothers milk is best but due to some reason if you are giving formula consult your Paediatrician because its given according to baby's weight etc. Don't give on your own.

Formula fed babies are more prone to constipation. Have you tried pumping the breast milk and feeding her? Or does she totally refuse to latch?

You can start with dexollac if you are having total lack of milk supply from breast

Because baby is not doing potty regularly... I am giving her similac advance 1
