Wow, brilliant BC!!
ETA: Eeeeeeeeeek! I just tried cutting M's hair and it is going really badly.
I used exactly the same technique a while ago and gave him quite a nice trim so I don't know what's gone wrong, but I'm close to just taking him round to the barbers and confessing my sins... Wah.
Oh and I still have a headache. Drinking plenty of water, actually got a decent chunk of sleep last night too. My neck/back is really tense and I'm still waiting to get this stupid gimpy mouth guard from the dentist to stop me clenching my jaw in my sleep. But I don't get why I'll get such a stabby-eye headache randomly half way through the day if sleep/tension is the cause. I don't want to keep taking paracetamol (not that it does much anyway).
