When our own twin niece and nephew were born, we baby sat them once a week, up to the age of five. They were fascinating to watch, communicating in their own language and showing off their special bond. I used to play music on our jukebox for them or play my guitar for them before they could even talk – both reacted to the music. I wish I had shot video of them in action while this was happening. Fortunately this family with twin girls did, with similar results so we can all enjoy the innocence of these two 11 month old girls.
You cannot be sad or in a bad mood after watching this.
