pmsl housemum at the thud yell bugger I forgot I left her sitting up! sounds familiar.
I remember when DD was born my friends said it was important to get them into a routine. For some reason we thought we should note down her routine at 3 days old by watching her. We wrote it down one night on a piece of paper which we kept. it went something like this:-
9pm 20mins left boob
sleep
9.45 15 mins right boob
sleep
10.30 20 mins on each side
sleep
ad infinitum for 12 hours
She just would not sleep all night every time she yelled, back to the boob - we though that was her routine.
It was only after we had a bit of sleep that we realised we were meant to impose the routine on her, not her on us!
We also kept her in a hat overnight (in September) because we thought she'd get cold, then read that they should never wear a hat indoors and cried for days that "what could have happened"
Oh and no one else could hold her right, feed her right etc etc.
I think I was like this with my PNB right until she started nursery school. saying to the teacher "she is the youngest in the class you know, are you sure you're treating her specially?".
DS born when she was at nursery school, at that point we just realised exactly how embarrassing we'd been with her and have switched to being totally blase about it all!
