charlotte, unfortunately there are always going to be those people who disapprove, or who just dismiss you on first glance... because obviously a young mum couldn't possibly have anything in common with women who did things the right traditional way
i had dd at 20, she was planned and we were trying for 2 years. we made a concious decision to do things back to front, we both felt we were ready for that stage of our lives and would prefer to have our kids moved out of home in our 40's and travel the world and relax with money and the knowledge that that part of our lives was behind us. we now also have ds who was unexpectedly soon after dd (got preg while bf-ing without any periods so was a bit of a shock after 2 years trying for dd ) but planned none the less.
tbh, i'm a better mom than most of the older 'successful' moms i meet, i listen to my kids, i play with them, i read to them, i give up on things myself so they can have a better life... very few of the older mom's who are quite set in their ways do these things... sadly some of them even act like the kids are an imposition on their lives
but unlike some people i don't judge every older mom just because of some i've met before, likewise not every older mom judges me, i've met some lovely moms who are twice my age, and some total cows my own age!
you know you're a good mom, don't let them make you feel any differant
