So I’m looking for any suggestions as to why this might happen and how to fix it please!!!
For the last 3 nights my 11 month old dd has been waking and crying between 12 and about 3. She doesn’t want milk, or if she does it doesn’t help her go back to sleep. She is dribbly so wondered about teeth but calpol made no difference and if anything she seemed more awake after that. No temperature. No poo. Room not too hot as far as I could tell. Happy to fall asleep in your arms but then can’t be put down. Not crying the whole time, only if she’s left or ignored so I don’t think she’s in pain.
After 3 hours the night before last she eventually went off with me lying on the floor next to her cot.
Two possible causes I thought of besides teeth - 1. She does struggle a bit with pooing, so wonder if she needed to go and couldn’t, but not a lot of wind, no straining, and on one of the days she was up like this she had done a poo and was still unhappy. 2. Milk - we are trying to swap her to cows milk. She has had milk on cereal etc before this so not the first time she’s had to digest it. We mixed it with formula for a day or two but then she seemed happy to drink it straight off so we swapped it. Could it be hurting her tummy to digest? Tempted to go back to formula but she starts at a childminder and I go back to work in 3 days so would rather not 
All advice appreciated! Anyone else had the same experience? 3 days before I have to appear to function like a normal human being and I’ve had less sleep than when she was newborn !!!
