Last night was even worse, if that's possible. 2.40am awake. Still awake at 4.20am when I pushed off to the sofa! I gave her some more teething meds before I went and assume she went back to sleep!!
On doing her teething meds tonight, I have found another tooth, so could've been that, but she was completely happy with it. She fed better tonight too and was asleep by 6.15pm, so fingers crossed all this dodgy latch and whatnot has been teeth related.
