How long did you pump every 2-3 hours ?

My little girl will be 3 weeks on Tuesday , I pump every 2-3 hours during the day and every 3-4 hours at night .

She doesn't latch after seeing multiple Lc so it looks like I'll be exclusively pumping for the next year (hopefully )

Just wondering how long you had to keep that routine ? When did your pumping schedule get easier ? How old was your lo when you were able to not worry about supply but also not be engorged

How did you drop pumping sessions ?
