It really is good to start introducing that little tooth brush as soon as any teeth appear.
It then becomes part of yours and babies daily routine.
You can use any milk tooth paste just a spot though and don’t expect them to spit out. There are many great products around but the one below can be held by baby and is less likely to cause choking it they inadvertently try to push it down the back of their mouth. It is important for you to help with brushing until your children are really competent.
Bring twice daily brushing in and also when you have a check up with the dentist ask if baby can go too, it is then less likely for babies to get scared in the future.
