Question about dating with a kid!

Hey guys! I am divorced, and am in my first relationship since I got divorced. I have a daughter who is one and a half.

I have recently started dating a man I go to church with. We actually dated in high school, and broke up. We both felt like the other was the one who got away. I'm super excited to be going out with him again. He's never married and has no kids.

He wants to start building up a relationship with my daughter, but we both agreed to give it a month or two, just to make sure things continue to go well between us before we start bringing her into our relationship more.

She sees him a few times a week at church, but they don't really spend time together.

My question is, what is something the three of us can do to help them bond? I thought about going to the aquarium, but I'm unsure of how she'll do. Like I said, she's a year and a half. Any helpful ideas? thanks!
