@tcr Most but not all. I used about 9oz of formula for a couple of overnight feeds where I was way too tired to get the pump out. But I was mostly giving the breast milk that I pumped in the bottle.
@benstiller12 I ovulated around week 10 and got a full fledged period two weeks later even though I EBF and my baby eats frequently through the night. I literally don’t get it.
