Elf asleep on floor

Since removing the side off her cot, the nights have been surprisingly good. But the days have been interesting.
Elvie is usually an angel for her nap each afternoon, sleeping for about 3 hours regularly, no arguments! However, the freedom to get in and out at will has seen a whole new development at nap time.
Day 1: Two hours and 20 mins of getting out of bed and leaving her room, only to be returned every single time by a tired but calm and determined Jussy. Result was an eventual nap on the floor.
Day 2: Forty minutes of playing quietly in her room, followed by 2 minutes of calling out 'mum' (with no response or reaction), followed by a nap on the floor. Note she didn't attempt to leave her room.
I think we're getting somewhere! Will keep you posted on tomorrow's develpoments.
