My brother-in-law, Devin, told me he was surprised by how quickly his first two kids became buddies. It's easy to imagine your toddler taking little interest in an infant that can't play back. That's pretty much what I expected. Vincent has proven me wrong though. Kate too. Vincent is keen on spending Kate's every waking moment together. And Kate looks up to and adores her big brother. Thus, at just a few months old they've already developed a special relationship. Buddies for life, I hope.
