Yes. In order to increase milk production, it is important to be removing milk from your breasts as many times in 24 hours as you possibly can. The exact schedule you do this does not matter, it is just important that it happens frequently overall.
Good to know.

I am a little unclear here if you mean baby nurses while asleep this long, or baby falls asleep, stops nursing, and then sleeps this long. Both would be normal typically.
Baby is asleep while on my breast. Once she starts to suck, she would shut her eyes then just continue to suck until it becomes very gentle to almost none. If I try to un-latch her, she would oblige but would cry immediately. Putting her back on my breast will make her stop.

Thanks thanks a lot.
