Strong

The ultimate strength-building toy is the rope swing.  Chloe couldn't do this stuff very well last year, but every summer she shows more strength, more endurance and more confidence.  Watch her go!

ONE-arm!!!

One arm again! and again and again!

The backwards kick-off.... scary!

One arm!!!

They can also develop super strong legs and toes with the rope swings. 
How, you ask?  Observe:

Grit and determination!!!

Notice Evan in the background??

Evan's just doing his thing....

Her toes are seriously primal.

Evan's been doing this stuff for years.  He even looks bored while climbing.  Ha!

{A challenge for Aunt Bryce on the next visit:  You've already done the one armed rope swing (and recovered), now it's time to climb using your toes!}
