Nath, we haven't cracked this problem at all.
Ava comes in with us less than she used to - perhaps seven nights out of every ten rather 19 out of every 20 (as it was up to a year ago) - and if it's just her then there's virtually no sleep disruption. But if it's Tallulah too (perhaps one night in four), then there's no way we can get through the night. Either I have to try and sleep in about four inches of bed, or they fight for space keeping us all awake, or - if I'm lucky - Lulu is so heavily under at the point at which her presence wakes me that I can carry her back into her room without further disturbance. I have gone and slept in Ava's bed before but it's the least-favoured option as it leaves Lulu on the edge of our bed and me out of earshot of the alarm.
