I like this thread. It's great to hear how diverse our babies' sleep schedule are. They are individuals, just like adults.
Up until about 6 weeks/2 months my daughter went to sleep with us, which was between 11PM and 8PM depending on how tired we were that day.
Then she switched to wanting to go to sleep around dusk (6:30PM here) give or take an hour...now with the time change her self-set bedtime is 5:30PM, give or take an hour. I try to be home with her by this time to help her go to sleep.
For the past couple months she gets up for an hour or two at 11PM... we think this is because her dad gets home from work late and she hears him talking and wants to hang out with him. Cute. So I go to bed, and she and daddy hang out - from what I hear from the other room, he sings to her, they walk around, they watch Youtube videos together, etc... He loves it cause he gets that special time with her when he's just relaxing before bed anyway, and she loves it because she gets her time with him. She's almost 7 months old now.
We all wake up in the morning around 7 or 7:30.
It's what works for us. That seems to be the theme of this thread- whatever works for the family. Love it.
