how much feed a new born should take ,weight 3.9 kg .as per top feed 90 ml every 2-3 hrs ? or less than that . as if i breastfeed he taks only 5-10 min with break . and vomits after that, while top feed he taks 70-80 ml with breaks.

A. 30 ML is the amount that you should be giving to newborn child if your child is not vomiting and able to digest 90 ML in a go then that is fine Naveen you should be feeding your child only on demand but still I feel 90 ML is quite a lot for the age
