March 22, 2010 --Sienna is just about to turn 8-months-old. Around 4 and half months, we introduced the "excer-saucer". She loved it... but after a while it got old, so around 6 months we put her in the "jumper". She loved that even more. Even though she was stationary, she thought it was a lot of fun jumping up and down while simultaneously squealing in delight.
