I see these activities online all the time. They come with labels like "Quick activity to entertain your toddler!" and "No fuss task while you cook dinner!" In my experience, it's all lies. Never has my toddler sat and colour sorted pompoms or put things into different boxes. But I try these activities anyway, just in case they might work.
This was another such activity. Write the name in pen, give the child spot stickers to put over the lines. It's practising fine motor skills. And it's all well and good, until your child starts putting stickers all over themselves.
At least she was having fun.
