@vanerahelson I know this is going to suck but... I turned into 1 of those people. I mean, I do usually wait until people ask, but still...
Yes, I woke up to go pee that often too. But I could go to bed at whatever time I chose, sit in the shower or tub to relax before sleeping which made falling asleep much easier, in the weekends I could nap whenever I felt like it and stay in bed as long as I wanted.
My sleep was 1000x better during my hellish pregnancy than it ever was after baby's been born. I wake up from every sound that he makes. Feeding him takes an hour so I have trouble sleepinf after his night feed. His naps are OK but if I want any me-time that isn't sleep I have to cram it in there.
Just... realise that for some people this is their reality and they might want you to be prepared. Tell them, "Oh dear, I hope my sleep will be better than yours was once baby is here!" and move on. And maybe if they add advice just list it mentally in cade you ever need it. But I hope you don't.
