Yeah, it look weird. Guess that’s by it’s not as popular, but while seeing my baby develop, I saw that they developed control over thumb and index, then middle. So, it’s the quickest way to teach them to count up 3.

Yes, from that bar scene.

I adopt representing 3 with thumb, index, and middle finger (German?), Instead of the usual index, middle, ring. This is easier for teaching my little girl as her hands muscle aren’t fully developed yet and have a hard time controlling her ring finger.
