When Ada and I went to our library's lapsit, they brought out the toys at the end, and they had these great clear tubes with toys in them to shake. Ada loved them, so I decided to make her some.
Empty Crystal Light containers
Some small items from around the house
Heavy duty glue (non-toxic since babies like to chew)
Step 1: Drink a bunch of Crystal Light. Now take your empty containers and rip off the labels.
