Thanks for the info. I did read it and I think it'll help, but last night was absolutely awful. lo has always been an easy baby and has been a good sleeper. the last week, he's been quite cranky. he does have 2 teeth coming out, so we have thought that's the main problem, but after last night, I'm starting to think it's more separation anxiety. He was up most of the night shreiking in this shrill way. up for hours, we fed him, gave tylenol, benedryl, rocked him. for a while he seemed like he liked to play, so we got him up for a while let him play, but he still wouldn't go to sleep. he only slept for several 30min or 1 hr spells. my nerves are shot. please help!!
