Thankfully, Em seems to teeth during "business hours" (i.e. when Sue and I are awake). This has occasionally included evenings when we've put Em to bed and she's woken herself up with pain.
Last night was the first night she started teething outside of business hours. It was about 1.30am this morn when we were woken with her pain-induced cries. A bit of drink off mum, some cuddles from me, and some baby Tylenol later and she was back asleep.
We've got eight teeth so far, and I hope this latest bout brings about a couple more at least. I just don't know how much more sleepless nights Sue, myself or Em can take.
