Eat well for ur breastmilk to flow. I experienced the same and gave my baby nan 1 she was stooling like crazy, i changed it and got aptamil, she was vomiting like mad. I had 2 accept the fact that i aint eating well nd so i ensured i feed well. Take pap morning and night, drink alot of water, u can had soya beans 2 ur pap, take oat meal dis increases breast milk. But the most important thing, EAT. Now my milk flows well. Bye bye to formula. My baby is just 6weeks
