I got pregnant with my first at 18, he's now 11, my second was born 6 days before my 23rd bday and she turned 7 yesterday. i married their father before the first was born though i was 5 months along when we tied the knot...but we were engaged before conceiving and not trying to prevent a baby(wanted to start a family right away)..it's almost 12 years later and we are still together, i had my tubes tied after my daughter was born cause the military let me and i knew i did not want to be having more after her, i love kids, don't get me wrong, i even loved teaching 2 year olds...i just knew that when my husband's medical discharge for his shoulder went through it would be way to difficult financially to add to the group. i've regretted it from time to time and wished i could have another, but that usually passed fairly quickly. i'll only be 41 when my youngest turns 18, my husband and i will be young enough to enjoy life and enjoy grandkids.
my family has this weird unplanned tradition too...
greatgrandmother was 15 when she started had 5 kids
grandmother was 16 had 4
mother was 17 had 3(granted all were unplanned and 9 yrs apart each time)
i was 18 had 2 kiddos
long story short...i love how my life turned out...yes waiting would have made some things easier, i went back to school at 23 years old with a preschooler and a baby..but i did it, i work a crappy job now, but we manage. i had the blessing to be home with both my kids when they were little and when i did go back to work i taught at the daycare my daughter was in and where my son had prek.
i say do what's right for you, no matter if you leap in or wait you will make your own path and you will do it no matter what to the best of your ability.
