Who knows......tbh our "routine" is very loose, I'm too tired, busy and stressed to figure it out. Anyway its roughly something like....
Awake between 6.30 - 7.30. 3.5 - 4 hours A time, then she will "mostly" sleep 1.5 hours. Then every 2/3 days she'll throw in a 30 min nap with the same A time (and 30 mins used to be UT for her)
We've never had 2 long naps - she'll then have a 30 min nap in the buggy or car at some point in the pm - I am normally out and about at that point I can't stand staying in all day. We cant go out in between naps and keep a routine as she'll fall asleep in the car at the drop of the hat, so if I have to go anywhere I make it in the pm (plus H is now at school so pm she sleeps in the buggy on the school run)
So she's getting a total of max 2 hours sleep a day - I know its on the low side, but her nights (if we get her back to sleep) are 11 hours minimum, mostly 12.
BT is 7.30 unless she's had an earlier pm nap, and I'll bring it forward to 6.30/7. She mostly goes down fine at BT, sometimes with a bit of shouting and complaining but we mostly leave her to it, or at worst I have to go back in and just put my hand on her back for a minute.
I feed her as it means we can all go back to sleep quicker - I'm so tired, I need every minute of sleep I can get. I'm happy to try and leave her, but I am always conscious of not CIO. I guess there is a line between "leaving her to cry" and CIO..........
