more than just cheerios

so for a while now the girl's main form of finger food has been cheerios or the "happy baby" puffs..I have decided they are ready to branch out into more options...although this does mean a much messier mealtime. They do love feeding themselves though, even though half of it ends up in their seats. What age is it that it becomes no longer "acceptable" to have food all over your face ;o) ...note: Paige is actually really clean...Emma is the messy one!
