I have been waiting for the day when these two could interact. When Dominic was more than a tiny blob of cute and Scarlett understood what I mean every time I say "gentle" or "don't sit on your brother".
For Christmas, Chris got a really fun floor air hockey set and the kids love it! I still give it a couple years before it is used in its intended manner, but for now it is great entertainment watching Dominic chasing the puck around the house and climbing in and out of the furniture to find the floating toy.
Also...this was fun to watch
