Peeing at night

Jessi

I'm currently 21w with baby number 2.

All day long, I drink plenty and am on my feet, moving around. During that time, I never have to pee more than i did prepregnancy.

However...

At night, i barely drink anything and am obviously laying down. I have to pee at least every hour..maybe more

Why??

Why do i pee more while resting and drinking less??

I'd rather pee more during the day so i could get some good sleep at night.
