DC is 17 months now, and for the last week they wake up at around 1am and awake for 1.5hrs. They were never a good sleeper, but since transition to one nap we finally started having good night sleep until split nights started happening.
DC wakes up around 7.30am, nap at 12pm for 1.5-2hrs and bedtime at around 7.30-8pm. We co-sleep but DC mostly sleeping in their toddler bed which is attached to our bed.
Does this sound like a sleep regression and just need to wait it out?
Any advice on how to survive split nights.
