One more thing:
We had an AWESOME tactic but it only truly worked on my oldest, who doesn’t even need the help.
It helped me stay unemotional.
“Ok kids, I’m going to try something tonight! I’m going to mark down how long it takes to get ready for bed... if it takes a short or long time, that’s ok. Then we will know how long, and we’ll start bedtime earlier or later.” I told husband this removes the emotional. Like “ok, if you want to take a long time, perfectly fine but now we know to start earlier.”
Oldest felt the incentive to get ready quickly. She felt so privileged to start bedtime later. Awesome.
Middle motivated for 1-2 days, because he sort of understands but not fully. He’s still awake now. Husband have been through sitting, walk away, he cried, husband sitting again. He says “I don’t sleep until a long time.”
3yo no concept of time, wasn’t really presented for his benefit. He will do whatever. But I tracked his times anyway. One day I realized, I could start bedtime at f’n 4pm, it’s not bedtime that is the problem. It is simply falling asleep, stopping the “water!” and “hungry” and “potty,” which cries are 50% legitimate. At that point it’s not bedtime, it’s just a neverending DAY.
