Yes I do judge. I was born to teenage parents. Didn't work out well at all so I've always had a very one sided view but even with age and maturity, I still think its a bad idea. Are there really that many contraceptive failures? I thought condoms and the pill were pretty reliable so I'm always a tad skeptical. I know someone in her 20's who has been pregnant 8 times and she says most were contraception failure. Actually when she went through it, it wasnt, she just didn't bother to take the pill properly so it failed a lot but she'll still say it doesn't work for her.
My cousin got pregnant as a teen, on purpose, no intention of ever working. She's lost interest in her child now she realises how hard it is and would rather spend her money on her nails whilst moaning she hasn't got enough money to feed her child. Another cousin got girls pregnant when they were all teens, he won't win any parenting awards and he lives off benefits and refuses to get a job. There may be many people on here that say they were teens, studied, were still high achievers etc etc but it's not something I've ever really come across in RL. I think MN often has a skewed view. In my school year there were well over 20 girls (that's just the ones I knew about) that got pregnant while we were at school. No way is that all contraception failures and they are stupid to purposely get pregnant at such a young age when they haven't finished growing themselves.
But OP, I wouldn't have actually made any of this known to you, at a toddler group, I would have kept it to myself. However I wouldn't have gone out of my way to speak to you because I never approach someone first and only generally speak to people I know, or if they approach me first. Which has nothing to do with you being a teenage mum.
I would be disappointed if my DD got pregnant as a teen or if my DS got someone pregnant as a teen, and I will tell them that beforehand. I'd support them (I was always told that if I ever came home pregnant I would be kicked out straight away) if it happened but they will know beforehand that I'd rather they did everything they could to prevent it happening in the first place and certainly not actively try to get pregnant, like many I have known did.
