I join you in 16 month sleep difficulties. Just like satya, my 16 month old little man keeps waking in the middle of the night crying- not hungry, not in pain- just unhappy. I was thinking bad dreams too. Maybe it is an age thing.

FWIW, when DS started crawling and pulling himself up, that ALSO caused complete sleep wreckage and disturbance. So maybe you have both the crawling and the "16 month old bad dream" thing going on all at once- lucky you!!!!

Hope our little ones sleep well soon.
