Bring the baby “alive” for their big sibling

I learned this tip from Cup of Jo and it worked wonders for us. I made up a silly voice for the baby and “he” is always complimenting his big sister’s dance moves, asking her questions about how the world works, and making funny jokes. Now that he is getting older and showing more of his own personality, the voice is starting to fade out naturally. But it really helped develop some camaraderie between them when he was just a potato.
