They love playing soccer together.
And sneaking out into the playroom when its time to do chores to wrestle around. (We have a rule of no wrestling allowed at our house...but that rule doesn't seem to stop them!)
Isaac has even picked up on Dominick's "face" he makes me when he gets into trouble. Their mannerisms are the same when eating food, when watching TV, and even when running around. God definitely knew that these two were going to be brothers someday.
What a blessing they are to us and to one another.
