Thanks so much!
You know what? I never think its teeth. And then days later I realise its teeth. Including last night which was our worst teething night EVER! (Have so far until now avoided multiple night wakings for teeth, just some grizzling and then some pain meds at about 10 pm). This was up at 9.30, 10.30-11.15, 1 and then 5.30. Argh!
So I think you might be right about the teething, even though I'm always in some kind of "its not teething" or "I don't think its teething" frame of mind.
Once this teething period is over I will wait a few days and see what happens, maybe push that nap out a little. But to be honest sometimes her nap is a little later and that makes not a lot of difference. Her sleeps this week have been less than 2 hours as well, which is a little on the unusual side... probably.... teeeeeeth
