Hi my child is 22 months old and brushing his teeth is a tough job for me.. He cries a lot and doesn't allow me to brush.. I somehow manage to do it but it makes him cry a lot and i dont like it. I have tried to brush along with him, show him other kids while brushing or videos of kids brushing.. Nothing works.. When he brushes himself he plays a little and it's not enough. How can I make this brushing session happy for him and I still this habit
