I am a fairly young mother. DD was born when I was in my early 20s. I have had a fair few judgey looks from people, as I look a lot younger (I'm now mid-twenties and look around 16/17) but no outright hostility. As a young parent, you do have to contend with a lot of judgement and so do often feel the need to justify your actions. When my DD was born, I had gained my GCSEs and A Levels, having attained very high grades, and had a place at a top 5 university, where I am still currently studying. I have aspirations, and I am incredibly motivated. Probably more so now I have DD. And so I completely understand the need to separate oneself from other young or teenage mums. There is a stereotype, and I have done everything in my power to combat it. My DD is academically a year ahead of herself, very active, is involved in extra curricular activities, eats healthily (for the most part) and is a very happy little girl. She wasn't planned but she was so, so wanted.
Being an older parent doesn't necessarily mean that you are a better parent. In actual fact, I have a close family member who was pregnant at the same time as me and told me my child would be "disadvantaged". She was 39 and now ships her DS off every single day, feeds him rubbish, and doesn't seem to have been ready for parenthood, even at 40.
With regards to younger parents not being "upmarket," I was privately educated, got excellent exam results, and come from a middle class family so I'm unsure about what the poster actually means by this.
Also, as a parent I don't really fit in with my university friends as we don't have a lot in common, and the older parents here have said that we wouldn't get on so I am a bit
