hello. my baby girl is 3 weeks old and i am ebf her. I am feeling lots of shooting pains down my breast is that normal? also there is a time of the day about 3pm that she just want to be on my breast. I have her 15 mns on each breast, burp her, change her and she keeps looking for my boob. I offere her the picifier and she sucks on it like she is still hungry and complaints.. this will go on for like 4 hrs, so i end up feeding her again and again and some times( like every other day) i end up giving her 2 oz of formula. I dont really want to do that and i try my best not to do it but i have 3 other kids who needs time from me and i just want the baby to take a nap so i can take care of the other 3. any adviceS?
