Some recommend that the best time for a new mother to start using a breast pump is two to three weeks after giving birth. However, the best course of action is to consult the pediatrician or obstetrician about when would be the best time to start. No two babies are exactly alike and some could have different needs, as could the mother, so it’s always advisable to consult a physician about when would be the best time to start using a hands-free breast pump.
