6 months EBF baby weight down

Natalie • Fire Wife🔥 Baby #3 ⏲

My daughter’s doctor honestly made me feel like crap at her 6 month appointment. I’ve been so loving being able to EBF this time around (had to supplement with son). Anyway her weight didn’t drop but it didn’t follow the previous curve she was on. She immediately questioned my supply and feeding schedule. My daughter totally leads the way on how long a BF session is and never seems hungry after. I work from home and schedule nursing sessions every 3 hours at least. I also co-sleep and she latches a few times a night. Anyone else have a baby that didn’t gain on a consistent curve? I’m starting to introduce some other calories soon so I’m not overly worried, but hate the implication that she is hungry or not getting enough.
