Bed at 7 and wakes up at 7 most of the time

My 4 year old and 2 year old go to bed around 6:30pm and wake up around 6:30am.

My almost 2 year old goes to bed between 7/8. And wakes up between 6/7

Bedtime around 7pm and wakes up at 730-8am

My daughter wakes up at 6:30/7 and goes to bed between 8-9:30

My 3 year old goes to bed between 830-9pm during the week and I wake her up at 830am. On the weekends I’ll usually let her stay up until 930-10pm and let her sleep in until 9-930am.
