I'm trying to set a sleeping schedule for my 1-year-old daughter. The last three days she was waking up at 8 and sleeps at 9 with two naps in between and it was perfect. But for no obvious reason she kept awake today until 2 am.
One main problem we had before trying to fix her sleep schedule is that she stays awake and plays with high energy until maybe until 3 am or 4 am although she wakes up from her latest nap at 5 pm. I know that there is a wake-up window for any baby that ranges from 2.5 hours to 4 hours or so. I don't understand why can she stay too active and exceed this wake-up window with much energy.
Any hints what can be the reason and how can we solve it?
