I think that pretty much sums up Evelyn. Exuberant. When she wakes up in the morning and is having conversations with the animals on her blanky. When she catches a glimpse of her brother and sister and goes wild with excitement. When she sees a nice warm bottle coming her way and loudly smacks her lips and grins. When her daddy puts her on his shoulders and she squeals with delight as he tickles her tummy.
She makes our lives exuberant. She makes our lives extremely good, overflowing, plentiful.
