reading about the 9-month results and i’m like ok but can you do this while postpartum? my supply is already sketchy at 4 months and i’m paranoid about adding anything that could tank it. also my husband’s out 4 nights a week so solo bedtime is already a war zone, not sure if now’s the time to add a new thing. before i even think about this, has anyone done tirz while combo feeding? how long before you actually see real changes?
