welcome back sara!! glad you had a great time away!!!
woohooo on teething!! as for the HAB and sleeping that must be hard is she still sleeping in your arms then? id try when she wakes pick her up, sooth then put her back down when shes ok, then keep repeating, it will take some time but hopefully things will get better.
millie still has between 4-5 sleeps , sometimes 3 if she has 1-2 long ones, yesterday was 4x 40 mins, every day is different!
