What do you think about bringing kids on dates?
I wouldn't say that bringing kids along on a date is weird. I would say that it is both awkward and not fair to your date. The purpose of dating is for two people to get to know each other in order to determine if they want to develop a relationship. You and the person you are dating can't do this if children are around because the focus of the date is on the children and not the two of you.
If cost is an issue for you, form a support group with other single parents and take turns babysitting one another's kids in exchange for your own date nights. Not only will you find free babysitting, but you will also have found a social network that understands the challenges of being a single parent.
If you have difficulty finding another single parent to exchange babysitting services with, consider someone who has a pet. Being as most pet owners travel or find that their animals are cooped up for long periods of time, these owners may be willing to exchange babysitter services. To balance out animals that need minimal supervision with kids that need constant supervision, offer a two-for-one deal. For every two hours of animal sitting, you get one hour of babysitting.
