I'm not sure if I'm going to breastfeed, supplement, or just formula fed my baby girl I breastfed my toddler exclusively till she was 6 months old but I don't think I'm going to be able to do it this time I really don't want to pump if I breastfed I wanted to breastfeed exclusively again but with my two year old, having to work full time six weeks after I have her, & just everyday things us as mother's & adults have to do I'm thinking what should I do ??? Any moms that have toddlers with a newborn working full time doing it on your own what do you do and how do you do it ???
