Hello, hope everyone is ok today.
I've been lurking but not posting as much as when I was bored out of my mind overdue. (Weird that!)
Huge sympathies for nixxxy, what an awful start to parenthood for you. You deserve a medal already. Hope the next 18-25 years is plain sailing!
DS2 has given me two nights in a row of waking 3 hourly. Which I'm very happy with! In fact, on a normal work night when I'd often get 6 hours sleep, with one brief feed (and straight back to sleep, Good Boy!) I'm tempted to call it "sleeping through" (so I can be that person who said "mine was sleeping through by 9 days old!"). However, I'm well aware this will all change in the next couple of weeks (if not tonight!).
Regarding routines, we've never had what you'd call a Routine with DS1. Of course, a loose one evolved, as Suz says, when mealtimes come in and bedtimes. He never napped properly so they were hit & miss but there came a time when we had to keep him awake after 3, and then after midday or he wouldn't sleep at night.
This time we'll have the school run and feeding DS1 so I imagine a routine will appear sooner with this one. (Although using the Glow app to log everything has been really handy to see when to expect a fussy time or some good sleeping times).
Huge respect to those of you with very little older siblings. I couldn't even entertain the idea of #2 before DS1 was 4.
