Can someone tell me what exactly I am supposed to be doing in terms of brushing DS's teeth? He is going to be one next week and he has two and a half teeth (one top one is just coming through). He's only had the bottom two for a month or so. The health visitor reminded me at his developmental check that I should start brushing them so I started a couple of weeks ago but to be honest I have no idea what I'm doing! DS is happy to open his mouth and let me brush for a bit but as he has so few teeth presumably I don't need to keep going for the full 2 minutes? He wouldn't tolerate that. After a few moments he clamps his mouth shut and then just chews on the brush. I guess that's ok for now but at what age do I need to become more serious about it?
