Brushing teeth

Jessica • Mommy of two girls 👧👧 and a lil boy 👶

My little girl is 15 months. We've been brushing her teeth since she turned 1. The problem is now she won't let me brush them. I struggle with her to actually brush instead of just sucking on the toothbrush. I don't know what happened in the beginning she would let me brush them and now she's not having it. what can I do??
