Symbolic present for daddy?

I'm looking for something I could get for my boyfriend to represent us becoming a family and to show him how much I love him, and that I'm not going anywhere. Considering he's 19 and I'm 18, we had a hard time with coming to terms with this pregnancy in the beginning, but we've worked everything out, and we are continuing to work at our relationship everyday. He's so great with absolutely everything and he just works so hard. I was looking at thingsremembered.com, I thought maybe I'd personalize something, but I wasn't sure what to get, and I wasn't sure if it's too girly. Any suggestions? Price is not really important.
