Hi there, sorry to hear you're having a rough time at the moment. Teeth can play havoc at this age as can all the developmental changes your LO will be going through.
Have you tried medicating before naps/BT to see if this makes a difference?
Would you like to post your EAS to see if any tweaking might help? It could well be the start of the 2-1 transition and if you are able to give a bit more detail we might be able to help some more.
