Breastfeed/Formula(3 week Newborn)

I didn't manage to give my baby any bm until 2 wks pp. And it was very little amount. Now I'm still pumping and accumulate enough for only 1 to 2 feeds per day. The rest is formula but I think it's OK. I was very depressed initially too but I've moved on. Some of our bodies just can't produce enough. Baby is 3 mths old and still healthy and developing well.
