So my 8.5 month old has been always a great sleeper (usually from 8pm-6am...occasionally waking around 4 or 5 but would nurse and go back to sleep til 7idh). How ever for the past week she has been waking up 2-4 times a night. It's exhausting! I feel like I have my newborn back. I don't know if she is teething (she had none) or what is going on. When she wakes in the night sometimes she cry/talk herself back to sleep other times I have to rock her back. Anyone else go through this? Any advice?
