before i delivered my baby, i also planned to have exclusive breast feeding. however , my bb didn't know how to suck and so i need to change to be pump mother. it's really very hard and stressful to have the idea that mother must do exclusive breast feeding. i didn't know but now i completely feel the stress. this affects our mood and may make us depress. so let's relax and strive the balance. if bb needs formula, that's just like we take vitamin pills instead of taking many fresh fruits and vegetables which we all know is better than vitamin pills.
