what exactly does this mean and PLEASE tell me it doesn last long. connor has been "sleeping through the night" for months. he just wakes up 2, sometimes 3 times, takes his binky and then goes right back to sleep. lately he has been getting up 10+ times. it is absolutely exhausting! he takes his binky and appears to be back asleep, i go back and lay down, and 2 min later he's fussing again. how long does this little wakeful period last? any tips on how i can help him sleep better?
