There are plenty of things that can make dating interesting, and dating a woman with kids is no exception. While the main focus of your relationship, especially at first, will be you and her, there is no question that her children will play a role.
Something to keep in mind is that single mothers typically have a harder time finding dates, or even dating at all. That doesn't necessarily mean that they are more desperate, but it does mean that they tend to be more appreciative of opportunities to go out on a date.
A lot of guys think that dating a woman with kids is a bad idea, and some refuse to do so. That's a good thing for you because it gives you the chance to meet some wonderful women who other men choose to ignore to their own loss. But kids alone shouldn't be the determining factor in who you are dating. It would be rather shallow to not go out with someone that is smart, funny and attractive just because they have children.
Of course there are some things that will be different, but they don't need to be a deal breaker. The biggest difference is that her kids can and should come first. So, if one of her children has a soccer game on Friday night and that's when you would like to take her out to dinner, you can be sure that she is going to watch her kid kick a ball around. That won't always happen, and she will have some free time, but just keep in mind that her kids are her priority.
There is a fairly obvious solution to these situations. You could–to continue with the previously example–make the soccer game the date and then go out for dinner afterwards. A lot of times the team will go out to dinner on their own and will be able to enjoy some alone time. However, if you want to show her that you care for her and her kids, then you could offer to take her and the kids out to eat after the game.
In theory you are only dating the woman, but you also have to make a positive impression on her kids when the time comes. While you're not dating the kids, how they feel about you will be important to the woman you're dating. Don't worry about this happening right away because chances are high that she will want to get to know you first before introducing her children to you.
With all of that being said, dating a woman with kids is a lot like dating a woman without kids. She still has the same needs and wants to have a good time. If you can provide her that good time and her kids happen to like you, then you will find that you are in a special and worthwhile relationship.
