Samm,
I'm a single mum. I so wanted to be a mum that I was willing to go it alone. I have little support. My mother is in the country and while she loves the idea of being a grandma it is not something that she manages with. I have my brother close by and he is great. I won't kid you it is hard and very tiresome at times. But it is worth every single moment of it.
The one comment I make when people ask me is that i just wish I had done it earlier. I absolutely love being a mum. My DD is just awesome and awe inspiring!!!!!
