The answer is the black & white mobile I made Aidan. He LOVES that thing. I call it his “friends” because he has the longest conversations with it and giggles and gurgles at it too. It’s made nappy changes a breeze and he gets visual stimulation for development at the same time. He’s decided he doesn’t like the Fisher Price Rainforrest Mobile that’s over his cot so I’m going to make another black & white one for him.
