That’s how Sam says "I love you." There is some variation too. With some regularity, if you say it to him, he knows and will respond. It happened first on Thursday (11/15) after John took off for work. Like other phrases and sounds, I just asked him if he could say it and he did :-). It took him a few times before he would say it after John or I said it to him — and he’s not 100% yet, but he’s getting there.
