One of our favorite afternoon activities these days is to go on a walk through the neighborhood and collect leaves. Ella uses her seat in the double stroller as a collection device. Now that the leaves have really started to fall, our walks are taking a lot longer since Ella can't bear to leave any leaf unexamined.
I especially love the red leaves, followed by orange and yellow. Ella is an equal opportunity leaf collector and doesn't discriminate based on color (she picks up the brown leaves and even the green ones that have fallen prematurely), but she is always on the lookout for a nice deep red leaf to make mommy happy.
