Our 13 month old who in the past has slept pretty well, maybe will have one wake up in past has suddenly become very difficult during the middle in the the night. In the past if she wakes up, one of us will go in to place her back down and maybe hold her hand for a min. She goes to be around 730-8, where she does very well. But for the last week she has been waking up at around 2-3 where she is crying and yelling, and does not lay back down or calm down, just getting more an more upset, until she is picked up or held. She does have her molars coming in, so are unsure if it that, or if she has separation anxiety, or just need of comfort. Looking for some insight, advice, or best practices. Please and thank you.
