Since Blanket isn't really into crawling, he is mastering voice and hand gestures. If you repeat his "dada" noises and then repeat them with a very simple gesture he will attempt the gesture/voice combination. I wasn't very concerned about this until I realized that he was imitating Tiger's shrieks. He is so good, that telling him "NO!" is egging him on. He has no qualms about shrieking in church, or at the store, or at the park, or anywhere. The funniest, or most frustrating part is when Tiger says,, "No shrieking!" to Blanket. He doesn't even realize that his bad behavior is what brought about the great shriekfest in the first place.
I am seeking input on punishing both of them. Mostly I am looking to punish Tiger, I am sure if he stops the shrieking Blanket will forget that he learned how for a couple of years.
So if you see me and Blanket is shrieking in church, please punish Tiger for me!
