BLT tucked the little ones in tonight, and TNT looked up at him with half closed eyes, and in a shy sleepy voice she said, "I love you... night night daddy..."
BLT looked up at me and he had tears in his eyes.
I think she was testing it out to see how it felt. Several days ago she asked me what she should call BLT now that we were going to be getting married, and I told her that she should call him whatever feels right. I told her to continue to call him BLT if she wants to, that there are no rules about this type of thing.
I think it's sweet, and I know BLT liked it. I have no idea if she'll will continue to call him daddy, or dad... or just go back to BLT. It will be interesting to see what she decides.
