Hi there Hun,
Well that is much much better

There will of course be a lot of accumulated OT which will take time to go. Also remember that it is a cold hard fact that 'sleep begets sleep' and always with S once he became able to sleep better he would look more tired and yawn more etc, as the sleep gates open, so to speak, so hopefully this will help the fact that you now have to take the sides of the cot! That is just typical isn't it, something else in the mix, just as things are going better

We also had to move S into a toddler bed when he started to throw himself out

WRT that, yes, a baby gate on the door is a good idea, and what most people do at this point. I wonder if you can get away with leaving it open, and only close it IF she continuously gets out of bed. if she prefers it open, you may be able to use this as a bargaining tool

. Just a thought. Yes, you just return her to bed, I think it will be a case of seeing how she reacts to this, in the light of her crying at BT YK

It may be that if it upsets her greatly, it is better than you just shut the gate and sit at the other side of it, not paying her attention and just using a 'sleepy phrase' eg "It's sleepy time Sweetheart" and wait it out until she lies down herself. I have known many LO's fall asleep on the floor and then be moved into bed, but sometimes depending on the LO's personality it can be the fastest route to show how things work once in a 'Big girl bed' so to speak. Also, she may astound you and love having the sides of her bed, make a big deal of her being a big girl now today, and make it exciting for tonight. Maybe you could get her something like this which my DS absolutely loves, it could encourage her to stay in her bed:

It is very relaxing and can be on chase, or one colour, the blue is a good one, not too bright, and it has a time to go off after 20 mins if you do so choose.
WRT her routine, I think a 45 min nap early in the day would disrupt everything for sure, and agree things are best left alone routine wise for now. She is getting so much more sleep over the last couple of days.
Okay, I hope I haven't forgotten anything, please do ask any other questions you may have Hun and good luck!!!
