My lo used to sleep through the night (from her last DF 10 a.m. - 6 or 7 a.m.) but has within the last 2 weeks, become very fitful from 5 a.m. onwards. She will make grunting noises, then put herself back to sleep again. This will go on and on until her wake time in the morning. It's so frustrating because from the moment she starts grunting (she grunts loud

, I can't put myself back to sleep again, and neither can DH. Sometimes I'll get up to go feed her, but by the time I get to her crib (usually grab a water bottle from the fridge first) she'll be sleeping again. I have fed her some nights, but even when she takes the feed, her sleep is still fitful afterward. Has anyone experienced this? Her naps are getting better each day (full morning naps, and 30% of the time, her 2nd and 3rd naps are complete) - so I would expect her to get better sleep at night. I worry she's hungry, but if she was, wouldn't she start actually crying? Any advice appreciated!
