Breastfeeding, AKA feeding your child with your milk-producing boobs.
Some moms choose to do it (and others don't, which is OK too!). I am one of the moms who chose to do it. I learned a lot. I experienced a lot. I am here to answer questions about what it was like from my own experience.
I fed my son straight from the boob and I also pumped. I eventually ended up switching to formula because I couldn't produce enough milk.
