I have to agree with Yukongirl. In my experience there have not been useful.
I would say there even less useful if your a guy. A lot of them charge you if your a man to use them and the ones that dont have like 20x more men on then women on them.
You should ask yourself something. If there are people out there that would not date someone because they have a kid, and am sure there will be.
But would you really wont to be with someone like that anyway. Its a bit narrow minded thinking along thews terms dont you think?
If I had a kid I would just concentrate on being the best dad I could. Thats gotta look sexy to anyone I would say.
Also you could use the kid to meet singles. Yea know single mums at the park or out side the school gates lol
Am sure the kid wont care if there getting a trip out of it.
