Twins are difficult; 2 year olds are difficult; throw in being a single parent too and I'm not surprised you feel isolated as I bet your days rotate around your children.
It's a lot quieter on here than it used to be but new people are joining every day and the only reason this region is quieter is that most of the former posters are now happily settled in new relationships. This region was one of the busiest!
Where do you like to take your children? a park or play area? we can pop a post up inviting others to meet up there so you can meet local single parents.
