In this colorful activity you can see many learning skills. Giant pipe cleaners are awesome for many play ideas. I know it might be quite difficult to be able to find giant ones but no worries normal pipe cleaners also works great for this activity.
Have ever tried to use kitchen utensils for creating activities? If not yet, you can start with a whisk for your baby/new toddler. You can tie pipe cleaners simply on a whisk and ask your kid to rescue them. It is great for developing many skills. It can help your baby to be able stay in sitting position longer time. Great for crawling times, too. You can put it a little bit far and ask your baby to catch it.
