What to call “bedtime”

I asked ChatGPT but I don't like its suggestions:

It's great that you're open to finding a suitable alternative to calling it "bedtime" for your niece. Here are a few suggestions you can consider:

1. "Restful Time": This term emphasizes the importance of getting enough rest while still sounding more mature than "bedtime."
2. "Dream Hour": This phrase adds a touch of imagination and excitement to the idea of going to bed, making it a more appealing concept for your niece.
3. "Sleepy Time": This option retains the focus on sleep but removes the "baby-ish" connotation, allowing your niece to associate it with relaxation and getting ready for a good night's sleep.
4. "Night Routine": This phrase focuses on establishing a regular evening routine, which includes winding down and preparing for sleep.
5. "Quiet Time": This term emphasizes the need for a calm and peaceful atmosphere before going to bed, which can be appealing to your niece. It would be helpful to involve your niece in the decision-making process by explaining why you're looking for an alternative term and asking her for any ideas she might have. By involving her in the discussion, you can find a term that both of you are comfortable with.
