Here's my advice. I've dated single fathers before but it's never worked out. Here are some reasons why. Don't make the same mistakes.
#1. If things work out tell her about the situation you are in with your Ex (mother of your child) so she knows what she is getting herself into. Agree with Naive if she's not a physco there is no problem. Been there. Not a good situation 2 get into. Glad I got out of that one.
#2. Don't dump the kid on her all the time and go out with your mates. Not when you are just dating the girl.
#3. Warn her when your Ex comes around to pick up the kids. I didn't appreciate when I turned up for one weekend and found another Ex's Ex girlfriend at his house without any warning. She seemed nice. Still it was a bit uncomfortable. I even noticed her glaring at me every now and then (when she thought I never noticed) out the corner of my eye when she saw how well I got on with their kids.
Just some things to think about. Along with others. The main one is just be honest with her and you'll be fine. Good Luck.
