Is bedtime 7pm?

I don’t think there is a right time for your little one to always go to bed at. 7pm of course works for some but a normal bedtime can be from 6pm until 8.30pm. Newborns tend to have a later bedtime and obviously even less consistency.
The time your little one goes to bed should depend on how much sleep they have had that day, what they have been doing and their wake windows/sleep cues.

There isn’t really an ideal bedtime!
