OMG really? So there's hope for me? DD is a lot like your DS wrt sleep. Maybe she will magically get better soon! Waking once would be a dream, LOL.
Yes, I'm sure there is hope for all of us! I didn't change a thing - DS just suddenly started sleeping better. It's been quite gradual, but we're definitely heading in the right direction.

DS ended up sleeping for 2 hours 20 minutes! Perfect .
