4am pumping I'm soooo happy

I went to my breastfeeding support group yesterday morning because I had no idea what I was doing, I didnt know how to keep my son latched, and I thought I didn't have milk. Come to find out my baby is tongue tied so he has to get it clipped and I was full of milk but my boobs are so saggy they weren't sore so I didn't know lol. I empty my boob out with breastfeeding my son yesterday and just woke up to leaking boobs I immediately grabbed my pump. Hopefully in the next week or 2 we can transition to breast feed only once we get his tongue situated.
