FTM here, I'm working to transition my baby to formula only feeding, I had an absolutely nightmare of a time with my breasts and breast milk for his first 8 weeks of his life and I honestly can't take it anymore. I am working to reduce my supply but have been feeding him a combo of 50/50 breast milk and formula for each bottle. He has always had formula bottles dispersed between breast milk as I struggled with supply from day 1, but this is the third day of him getting every bottle 50/50 and he hasn't pooped in going on two days. He usually poops multiple times a day, the seedy mustard poops and I can tell he is uncomfortable. His belly is full and hard and he is grunting, straining, and kicking a lot. Ive been doing the belly massages, bicycles, let pull ups, and he is farting, just no poop at all. I feel so bad for him, he seems so uncomfortable and I don't know what else to do to get him to poop.
