Hi! I am a lactation consultant and BF Coor. for an upstate NY, USA, WIC program. I work with low income women and their babies. Many of the moms I see ask me if it is OK to use some formula bottles while they BF. I tell them the best is only breastmilk, but if they really feel the only way they'll BF is if they can use supplemental bottles then to wait until the baby is well established at the breast and the milk supply is regulated (4 to 6 wks?). I then encourage expressing breastmilk for the bottles, but many of these moms really insist on the formula. One of our local pediatricians tells our moms that they have to make a choice, breast or bottle. I want to encourage BF any way they'll do it. My hope is that they'll fall in love with BF their babies and change their minds about the formula and if they don't then at least their babies have received some of the benefits of BF. How do lactnetters feel and what are your recommendations to moms that ask this question? Thanks Susan Niedzielski, CDN, IBCLC
