Gradual retreat is what I'm working on now, but also letting her know that being sneaky won't work.
We're fully potty trained for daytimes, but still use a nappy at night. It's been a very unsettling few weeks particularly (and we've only been potty trained 8 weeks), and I don't want to put added pressures into the mix.
Bedtimes this week have been varied because of all that's been going on, but we're now getting to a far more manageable time.
Sunday: 10pm
Monday: 10.30pm
Tuesday: 11pm
Wednesday: 11.30pm
Thursday: 9.50pm
Friday: 9.30pm
Tonight: 9.10pm
Daytime naps have been kept to a minimum.
Evenings have been tea at a reasonable hour, play for a short while (quiet toys only - jigsaw, teddies, building blocks), get into nightclothes and nappy, drink of warm milk with quiet classical music on, a story and a cuddle, teeth cleaned, last minute wee. Then we have cuddles on the bed with the light dimmed, before transferring to the cot. I sit on the floor beside the cot holding DD's hand. The musical nightlight goes on and I stay until it's finished. I then switch it back on and leave the room.
Last night and tonight she was insistent that she needed 'another cuddle' and then 'need a wee on the toilet, I do! I do' but having already checked three times before bed, and taking her again between bed and cot, there was nothing coming. Tears and tantrums. I calmed her down, got her to lie down again, and put the musical nightlight on and told her that if she didn't lay quietly I would have to take away a toy. It's been quiet ever since.
