I'm so tempting the sleep gods by posting this, but I had to make of record of this. I put the babies to bed at 6:30 last night, Emma woke at 11, then they both slept until 6. We fed them and put them back down hoping they'd go back to sleep, but not really expecting to. They slept until EIGHT!
Emma's been sleeping better now. She typically wakes twice a night around 12 and 5, but Cora has been waking around 6:15, so that 5am wake-up has been tough on both of us since I get her up too. I can let her sleep an extra half hour without it messing up our schedule, but they'll be up at different times throughout the day if I let her go longer than that. Some nights, she'll wake around 2 instead then they both wake at the same time in the morning. I'll take it! It's so much better than the every hour waking she was doing a few weeks ago.
