@manga006 4-6 months was my favorite too. Currently at 15 months, LO has so much energy and opinionated. It gets hard having a slow day at home, it is easier to spend the day outside.
@sthsu We have similar schedule.
Wake 8 am
First nap 11am - 12:30pm
Second nap 3:30pm - 5:00pm
Bedtime 10:00pm
We have experimented with 9pm and 9:30pm bedtime but leads to waking up at night.
