Re: is it possible...
It is possible for a breastfeeding mom to get pregnant very soon after giving birth. It's very unlikely, but possible.
It is also possible to nurse through pregnancy, though many moms lose some or all of their milk supply and therefore must supplement with some combination of donated breastmilk (preferable) or formula (less preferable). I have seen it said that about 80% of women who become pregnant while nursing lose some or all of their milk supply.
