Sprite was having a hard time with her wooden puzzles the other day because of the safety knobs, and it gave me a good idea. She would hold the pieces by the knobs, but when she tried to turn them to get the pieces in their spots, the knob would turn but the puzzle piece wouldn't.
I put a little dab of wood glue in the center of the back of the safety knob to prevent it from spinning. For some of the pieces, they also needed glue around the outer ring of the back of the knob.
It was a world of difference after they dried! Sprite can finish her favorite puzzle in a minute flat, whereas before she would struggle until she got too frustrated to continue.
Such a simple little fix but such great results, I had to share.
