'T' as far as dating with young'uns goes, there are men who will be scared off immediately, men who will shy away later, ones who will think of you as a short term thing only, and others who have DC themselves who would prefer someone who understands the pressures they have themselves.
I would recommend making sure you have regular childcare though - I started dating someone months ago who had a 6 month old and we really liked each other but her childcare was iffy so she kept having to rearrange things at the last minute, after a couple of snatched evenings over the space of a month it just became silly. I kind of wish I'd kept on with it, apart from my relocation, as she was very sweet and attractive but it was just impossible to plan anything.
So- try and find a sitter who you can trust, a sitting circle or something, and take it slow. Weed out the milfhunters and there are decent blokes out there.
