So, I co-sleep with my 5-month-old, almost 6 months. She always wakes every 2-3 hours for a nursing session, even if it's just comfort suckling to help her transition back to sleep. Well, within the last two nights, SHE HAS STOPPED SLEEPING! One night, she was tossing and turning. She kept stretching and yawning and falling asleep, then five minutes later frantically turning her head back and forth really fast, then crying, then falling back asleep. A few minutes later she repeats, then turns over, fusses, and falls asleep. That day at daycare she took two ten minute naps. Again, same thing last night. But then today she would catnap for ten minutes. She only slept a total of a half hour ALL TOGETHER. Then, I thought she'd sleep great since she's barely slept. 8-12 without waking even once, but after midnight she was tossing and turning and all that again. So by 3:30am I couldn't take it. I came downstairs to scour the internet for any information or help. Nothing turned up besides sleep regression, etc. but she's NEVER slept through the night more than 4 hours. She has a schedule, 1 or 2am, then 4am, sometimes 5am too or 6am. But I didn't mind that because she would get on the breast and go right back off into sleepland. We were both well rested. But suddenly she has NOT BEEN SLEEPING. No changes in anything, diet, schedule, etc. SO WHY THE HELL WON'T SHE SLEEP?! She's grouchy and loud, but seems to be having fun right now. WTF? PLEASE HELP:( What do I do? (PS Stopping Co-sleep or trying CIO are both methods I refuse to use so please do not mention either). THANKS!
