My 2.7 yo DD (not sure about the dear atm) has gone from sleeping really well to fighting it and us completely. When we've had blips in the past we've used rapid return which has always worked. She has had the side off her cot for months as she is tall and was climbing. It actually made her like bed more.
Last week, after the heatwave, she just refused to go down at bedtime. We must have returned her to bed at least 60 times in quick succession (also with periods of taking a step back because we didn't know what the hell to do) the first night and she gave in around 10pm. The next night was the same but she didn't cry at all, just running back to the gate at her door. In the end we went downstairs for a little while, I returned and pottered around whilst ignoring her. She got upset, I put her down, she fell asleep. The third night, she just wouldn't stay in bed. We were worried about separation anxiety so thought gradual retreat would work. It did, but then she started waking in the night and we were trying gradual retreat for hours. We've given in and slept on her floor but she doesn't really sleep with us in the room (I was in there lying on the floor 3-5am before she slept).
We are at the end of our teather so controlled crying seems like the way to go. We have made a simple sticker chart with a picture of a toothbrush (easily achievable), a bed and gro clock. We have gone over the what they mean with her, shown her the toys she can get as a reward and gone over and over it with her. She understands it.
Her bedtime routine is fine, she gets pyjamas on, uses the potty, has milk, cleans her teeth, turn on fairy lights, 3 stories, then battle commences. The first night I put her down at 6.20, she fell asleep at 11pm. Last night she fell asleep at 10 but woke at 1.30 and we haven't got her back down since.
Ani know this is long so appreciate anyone getting through it all. HELP PLEASE
