Hi. My baby is 37 days old. whenever I do breastfeed my baby just suck for 3-4 minutes then sleep and then after 10 minutes again cry for milk. Like this I have to spend 2-3 hour on feeding and at the end to keep her calm have to give formulae milk. But whenever I use to do pump m getting 100 ml in morning ang 60-70 ml in evening. And that's why I have to pump and give her milk like this .no latching problem. She leached properly. Kindly suggest what to do so that she do the breast feed directly. Why she sleep after 3-4 minutes of sucking?
