Hey nic - DS is the same with sleep. He has a long stretch first - these days 5-6 hours, or at least 4 - and then multiple wakeups after that. But it's soooo much better now cause he usually only wakes up once more and goes back to sleep quickly (not taking 2+ hours like it used to...). Hope this is a sign things are really getting better for you
And yeah, why not 3?!
