sleeping through the night & pumping

Alicia
So I cannot believe I'm writing this as I was the one last week who had a baby up every hour in the night. After 4 nights of gentle sleep coaching she has slept through the night 2 nights in a row 🙌🏻🙌🏻🙌🏻 my question is if she makes a habit of this I'm thinking of setting an alarm to pump in the night but from experience what is best to do to maintain supply? In the past my supply has dropped quite quickly so I don't want that but I also would like a big chunk of sleep!! 😆
