Is he trying to flirt or just being nice/social?

A newer person at my job kind of seems to be interested in me, but I wanted other opinions.

When he works with me, he is always friendly and looking for any excuse to make conversation. He will ask me to "show him" stuff he already knows how to do, he'll ask me questions he already asked me, he'll say good morning, he seems to want to talk to me whenever I'm around. I've seen him staring a few times. He has facial hair and I've noticed if he sees me coming he'll mess with it/adjust it. He laughs at stuff I say even when it's not THAT funny.

I've noticed he's starting to get more personal now. He is starting to ask me about my personal life and stuff. We both have kids and he was asking me about my child today (how old are they which turned into wanting to see pics and saying how cute they are and that they look like me). He said his looked like him too (possibly dropping hints for me to ask to see pics?). Then he said don't take this the wrong way but you don't even look like you've had a baby. Does that mean he finds me attractive? I noticed he's also recently started wearing cologne when I've never noticed him wearing it before.

Is he trying to flirt with me? Odds that he could be interested outside of work?
