When to drop MOTN pump?

M

My 13 week old daughter has been sleeping thru the night for about a week. I am an overproducer and have 1300 oz frozen. I’m still getting up twice at night to pump (LO was getting up once at night before she started sleeping).

Should I wait until after the 4 mo sleep regression to drop MOTN pumps? Other things that factor in: we’re going to transition her from her rock n play to her crib in the next week and she’s been at daycare for about a week.
