My 3 month old went from starting on a good sleep trajectory (a five hour and 3 hour stretch at 8 weeks regularly) to waking between every 15 minutes and every 2 hours. What I'm trying to figure out is what causes the frequent night wakings. She was fighting her arms out of her swaddle and getting the fabric over her face in the process, so for her safety we taught her to sleep without it. Plus she started sleep crying for gas pain or some other cause in the very early morning nearly every morning that we rushed to comfort. With all that her sleep habits deteriorated. They have been getting worse and worse since 9 weeks and at 14 weeks I am at my wits end with the double digit number of night wakings. Reading that some people consider 4 bad was hardly comforting.
I've seen Marc Weissbluth's theory that the frequent waking issue is from some form of overtiredness in Healthy Sleep Habits, Happy Child. I've tried his solution, too, which is invariably to move bedtime earlier. Well Her bedtime has consistently been earlier than 6:30 for well over a week with no changes. I'm sure the completely fragmented sleep is making her overtired, but earlier bedtimes are doing nothing to help. Her naps are not yet organized (I'm despairing that they ever will be at this rate) and so she takes 4 to 5 30-45 minute naps - if she'll take them - that I offer whenever she starts yawning, looking glazed-eyed, or rubbing her eyes.
This question's accepted answer suggests hunger as one possible cause. My little girl is skyrocketing up the growth chart and eats every 1-2 hours during the day on demand. I feed her 2-3 times at night, but not at every waking. I sincerely doubt she's hungry, but I'm open to being wrong.
Baby does have a pacifier, and popping it back in often soothes her back to sleep. Would trying to wean her off of it at this early age perhaps help her learn to self-soothe, or would it just make sleep worse? I am totally fine if she wants to suck on her fingers or thumb and get us all a little sleep, but so far every time she finds her thumb it does nothing to help her go back to sleep. She's not really coordinated enough to keep it in her mouth.
Could it be the 4 month sleep regression come to call early? An early start of Wonder Week 19? Is there any solution other than to soldier through? Is there an age-appropriate form of sleep training worth trying?
