Postpartum Periods - Can they be delayed for more reasons than just breastfeeding?

This is one of the most common questions that I get from clients and followers. And one that I’ve actually been quite interested in myself. I’m in my second postpartum currently and I’m interested to see when my first period shows up this time. With my first, I didn’t get my period back until almost 15 months postpartum. I pumped and nursed throughout my first postpartum period and co-slept through 15 months.
