One activity that we do daily is coloring. I think it's great for Camille -- she can learn colors, body parts (color the hair brown! color the lips pink!), hand/eye coordination, all of that good stuff. And it's great for me ... how else do you think this blog post is getting written? Yep, she's coloring in her high chair as we speak!
We typically transition straight from breakfast to coloring. So she stays in the high chair and I just swap out her cereal bowl for a coloring book and tupperware of crayons.
Coloring books from the dollar store are our favorite, but I also have had a fun time printing pages for free that you can find online. Just google "free coloring pages" and you'll be amazed at what you can find. We have an upcoming beach trip, so we've been doing lots of beach scenes recently to get Camille pumped for it and familiar with sand castles, pails and shovels, shells, the whole bit.
Ian has also printed out some Halloween pages for her already. Never too early to get that started, ha!
