I love this idea from Twodaloo as soon as I saw it! Perfect for toddlers but can also be used for many purposes in a wide range of ages depending on your needs.
Twodaloo has some great ideas on how to incorporate lots of speech and language games using these eggs. These would be great to make ahead of time and keep them in a bag ready for playtime if you need it!
