No fancy video, but I thought I’d pass along that last night when Amy was making some funny faces and noises for Alex, Alex responded by imitating and doing the exact same thing back, which caused Amy to yelp and squeal and hop with joy, which caused Alex to get a huge smile on his face and jump and hop and giggle. The two of them proceeded to go back and forth with who was doing the odd smacking motions and sounds with their mouth, and who was laughing and giggling and squealing. This lasted probably a good fifteen minutes before Alex got bored and decided he would rather do something else. :-)
