Why on God's green earth you decided to go big with the toothbrush heads. Did you think that after every 3 months that children mouth grow big/large? Very angry because my daughter refuses to use it as it's too long for her tiny mouth. Bring back the 3+ replacement heads now please.

SO MUCH BETTER and easier to brush my kids teeth with this size head. Got them when they were 3 & 5. Wish I had got them sooner. The small adult heads are smaller than the “standard” kids’ size, which I don’t understand.

Purchased it for 2 toddlers. Small compact size is perfect for their small mouths and teeth. Easy to brush on and around their small teeth. Have been using it for about 2 months. Reduced the rating by 1 star because the package only came in one color. Will review again at the end of the 3rd month.
