Ok, so I am not a lone parent but thought you might be the best people to ask.
I have no children myself but my partner has 3, who he cares for fulltime. We are long-distance so I only spend time with the kids every other weekend or thereabouts.
I have no children in my family, no friends with children - meeting his kids was my only real contact with children since being a child myself! I feel a bit 'thrown in the deep end' at times, but enjoy spending time with them.
I would love to befriend a family / parent, to have a bit of experience with kids outside of my relationship, to have a parent friend (other than DP) to talk about kids and kids things with.
I've seen things about 'adopt a granny' - I am nowhere near being a granny but is it a strange idea to 'adopt an adult friend'? I suppose I am thinking of lone parents who may lack support from other adults, may not have family around etc.
The only way I can think of going about it is babysitting...
I think the answer to my thread title is going to be 'yes'.
