DS1 didnt get teeth till 11 months and we started trying to brush them at same time. Wasn't hard when he only had 2, but as he got more it got harder!!!

Now at nearly 2 he wants his toothbrush in morning when I am doing my teeth and he will suck on brush and move it around a little bit but not much, I then brush his teeth but its only a small window of opportunity until he clamps down on brush or runs off.
