hey mommies, my son start daycare in one month and i'm acutally breastfeeding and still want him to have my milk in bottle at daycare. i started pumping to make a stack in my freezer but i realize i dont pump as much as i use to pump. 🙁 when Justin was 3 months i use to pump every morning and get at least 8oz. now i have shortly 4oz. ☹ any tricks to boost my milk supply? baby is fed on demand.
