my daughter is almost 6 weeks old and i am breastfeeding her (finally after having mastitis 3 different times ). I really wanted to breastfeed but in the beginning she wasn't gaining weight (on account of the mastitis, i think) so i had to give her formula. Now that i have her back on the breast (because i have been feeding her frequently to increase my milk supply) i am wondering if it is possible that my milk supply decreases around the same hour everyday (about 5 o'clock). With all of my effort, she gets frustrated at that hour like she isn't getting enough milk and i am forced to give her formula. Is this normal? and how long will this last? and how long does it usually take to ween a baby off formula and get her back on the breast?
