Y so many people look down on younger mumz? READ!!!?

I am 17 & pregnant 4 the 3rd time.. As ii have had 2 miscarriages.. All my pregnancies was planned.. & i cant wait to have a family of my own.. I have read a few questions on here & so many people down young & teenage mums.. When why.. They are just as capable as the older mums.. As long as they are grown up & can look after themselves aswell as baby.. & still have time 2 have more if they want to.. The older u get ther harder it gets 2 get pregnant.. Your fertility levels go down at 25.. & u COULD run out of time 4 having your young 1's.. Or something bad could happen which could stop u having babys.. &Younger parents are more active so wouldnt that make u a fun parent when your child is old enough 2 play etc.. U will have heaps of energy.. & able 2 make your child laugh & have fun.. Rather then sticking them in front of the tele watching blues clues.. I am NOT downing older mothers.. Koz most of them r brilliant.. I am just saying that us young 1's are just as capable as u r. & most older mums had thier 1st at around 17 - 18.. & some teenagers have better income than older women.. Some older women just want the income so why is it that all us teenagers want is money & a house.. Because.. Its not true i am 17 earning �1800 a month & renting a house untill i get a coucil 1.. But by the time i get that i will b able 2 buy 1.. Soo i am not counting on it.. U all just NEED 2 realise some of us have got our heads screwed on but just want a baby young.. Look on the bright side.. We will b young nice lookin mums!!! :)
