How did the night go? I always think it's better to put them down when they're ready for BT, as pushing them tends to make them OT, which often makes the night worse. Your BT is going to be naturally earlier for a little bit, since you cut out the 3rd nap. Most LOs will make up for the lost sleep at night, but not all. Have you ever tried an early BT? From your routine yesterday, I would've gone for 6:30 or even 6:15. Even if they still wake up at 6:00-6:15 in the morning, they're getting a much better night's sleep and will be better able to make the longer A times during the day.
So, the first A time today was 3 hrs. 25 minutes. The second A time was 3 hours and this last A time will run close to 3 hrs and 45 minutes as I try to get closer to 7:00. Any suggestions?
I know they've had a big jump in A times, and that can take a little while to settle in, but these are much more appropriate for their age. I still think the second A time needs to be a bit longer, closer to 3.5hr (you don't have to go there all in one jump, just by 15min or so every couple days), because that nap isn't a full one and then you're ending up with that really long A til BT. I always think it works out a bit better if the A times are more even throughout the day.
