I have two children - 5 years and 2.5 years. Once bought this brush, I think soon the older, but they were divided between them, and I did not object, so she went to all the same younger. He successfully cleans her teeth! brush head is large enough - if you like to make each other two nail on the thumbs, but the calf is 2.5 years with success it enjoys. Brush sufficiently tightly packed, and the bristles though soft, but perfectly clean! It is convenient to hold in your hand. I tell his son put a finger into place and then brush becomes just a necessary reversal. She won many of those brushes that are sold in Russian stores that have a desire to order it, and more!
