my baby 2 and half month baby started crying after 7 to 10 minutes of feeding from one side and doesn't eat from that side when I offer another side he started feeding what is the cause. Is he get enough hind milk or not. he looks very thin.

A. To collect hindmilk for your baby, you should use a breast pump and separate the foremilk from the hindmilk as you pump. When you begin pumping your breast milk, it will be thin and watery. ...Now, place a new collection container on your breast pump and continue pumping until your breast is empty.
