How do you do it?! My 9 mo has got 6 almost 8 teeth, we do blw and he's breastfed so us putting anything in his mouth is alien to him and he gets upset and just clamps his mouth shut so I don't push it as I don't want it to be a big issue. He has the occasional chew on the toothbrush and I got one of those teether toothbrush things but there's no way we are anywhere near twice a day. Any tips?
