Pumping question

My daughter sleeps 12 hours each night now. I am a SAHM and EBF. Usually I get up around 3:00AM to pump, so I have some to stash away and my breasts aren’t so full.

I know that my body should regulate itself and I should still have enough milk during the day to feed my daughter...however I am so afraid of my supply dropping.

When you baby started sleeping through the night, when did you pump? Did you have any supply issues?

Getting up to pump is waking up my husband, so I would like to maybe pump before or after feedings during the day.
