The Bubby has guided us in to a routine of her own.
Her last feed seems to be around 5 or 6 (depending on how the day has gone) and it's her fifth or sixth feed of the day. I have her in her seat while I get The Toddler's dinner ready, and she's usually asleep (or well on her way) once it's time for The Toddlers bath.
Then she sleeps through until anywhere between 3 and 6am, usually with another two or three hours of sleep after that.
She's also ready to nap an hour or so after her feed, so she does spend a lot of time asleep. I feel bad putting her into her bassinet at her first tired signs (usually going to town on her hands/fingers/thumbs) but 9 times out of 10 she selfsettles herself to sleep within two minutes, with not much of a fuss at all.
She was a bit upset some of her awake time today, but that seemed to be because she is snuffly - I have a cold, and it's like a final injustice for breastfeeding mums that there is nothing you can take (apart from panadol) to help recover. And sleep is inevitably hard to grab with a baby.
