Blink and they're all grown up... this week our "Little Avengers" all opened their eyes. (Just when you thought they couldn't get any cuter!)
They're also starting to try and push themselves up on their stocky little legs - almost taking their first steps. By next week, they may be running already!
And last but not least, this week they've discovered there's more to their voices than simply squeals, and have begun to attempt the littlest of puppy growls and barks.
Off the charts adorable, folks.
