In a really strange way I kind of relate! the young mums in our area are about 21ish so you would have fit in nicely. I had the complete opposite issue when I had my baby, I was 28 and the youngest in the group, the next youngest mum was 34 and all the rest were 37 having their first baby. They were all established and wealthy driving around in SUVs, married to CEOs and living in gorgeous 4 bedroom mansions so I found it really hard to relate to them - I probably still would, even though I'm really old now.

I'm so sorry that your mum's group look at you with pity!! It's ridiculous if it was your choice and you are happy about that now. Mum's groups can be a bit hard to deal with at times, at least by the time your kids get to preschool it shouldn't really be an issue anymore for you? I hope you find some great mums whatever their or your age that you can relate to.
