I currently nanny B/G twins who turned 3 last month and have been with them the past 2 years. Recently they started having a harder time going to sleep at night and also waking up for hours at a time during the night (6pm bedtime) so they pushed their bedtime back to 8pm and things were fine. Now the parents want more alone time so they want their bedtime back to 6pm so they have decided to cut their naps out. The problem is, the children are still refusing sleep until 8-9pm and also waking during the night. The parents wake the children at 6:30 before I arrive and refuse to let them nap. The children are exhausted and don't want to play, crying almost the entire day begging to nap. The parents still say no. How can I go about keeping them awake when they are exhausted, screen time is also not an option and any quiet time results in them falling asleep. Also, any advice to get them back on a good sleep schedule? Thank you!
