hi. i've noticed my milk supply seemed to have decreased since getting my period 5 weeks after giving birth. so unexpected considering i'm breastfeeding. i did get a massage so that might have stimulated something. my 6 week daughter is gaining weight appropriately and # of diapers being changed daily is fine. my concern is not able to provide enough milk between each feeding. i do have my husband give formula at night - she gets about 3-4 formula feedings alternating with breastmilk. i'm not returning to work for another 1 1/2 months and that will be my concern as well. unfortunately i'm manually pumping until i get an electric breast pump.
