I would like to preface this with saying - I adore my son, love him to bits, and he has brought me SO MUCH joy. Please don't think otherwise from what I'm about to say. (And I'm really not trying to be a downer - just sharing my experience)

I was slightly older than you, and single but otherwise not dissimilar. I lived with my mum, who was supportive and going to totally help out by being an extra person to help whenever required etc. I was on CL (still am) but had minimal/no bills/rent etc to pay so I justified the low income as being all disposable. I was a homebody who didn't go out with friends really or to clubs etc, and figured I could take a baby/child with me if I decided to travel. I have mental illness but it was managed so I thought I would be fine.

When I had my son - my promised support from my mother just vanished, for reasons beyond our control or ability to predict. I ended up having to move out which was expensive and *difficult* with a small child around. I now have a partner but her income is not much more than my CL. I have had what seems to be a relapse of my depression and some days I considered things you don't even want to know about. I've had to decide between doing swimming lessons etc with my son (that I would *love* to do) and putting him in daycare twice a week so I can hold on to my remaining shreds of sanity, and just sleep. I can only afford one on my income.
So he misses out so that I can stay 'together' enough to be a good mum.
My friends disappeared... They didn't get it. I spend most of my day alone now, and even on the rare few nights when I would like to go out... It's so much harder to organize. We pay $60 for a babysitter if we have a nice dinner as a couple. Guess how often it happens.

I don't wish him gone. I wish I had WAITED. I wish I could have another few years to be me and not 'Mum', and have him come along later, exactly as he is, but... Just. Not. Yet.

I thought I was more than ready, but I didn't understand the sheer enormity of the change that being a parent would make to my life.

Take your time. Do as the posters above all suggested - they have some great ideas. And when you do have kids - it's a beautiful, life-changing experience. So you want to be damn sure you're done with enjoying what you currently have
