Discovery bottles are great for curious little ones.
I like using small water bottles for A's little hands.
One bottle is water free and filled with pom poms & sparkly pipe cleaners.
The other one is filled about 3/4 of the way with water.
It is a Christmas themed bottle with red & green pom poms and beads.
Bonus: You can have your toddler fill the bottle.
This is a great "busy" activity they will love!
*For safety concerns you can glue the lid to the bottle when closing.
