Is it normal i think it's shocking a 33 year old has a 18 yr old

An 18 year-old child? They would have become a parent at 15 so yes that is shocking to most people in the western world, it’s generally considered impolite to express such shock to them though.

Yeah makes you wonder about the type of parenting she got. And that type of thing tends to pass onto further generations.

Not particularly shocking in Australia.

Not particularly shocking in America or Canada either, and certainly not in most of Europe either.

Why are you so surprised?

I became a grandfather at age 35 based upon the older ages of the 2 step kids I raised from ages 2 and 7 into adulthood.
Have had 5 grandkids for a few years now.
Was a proud but ailing husband and father for 23 years to the fullest of my devotion and service, but was relieved of my duties this last Christmas.
What has so far been the 40th year of my life has been perhaps the most perilously difficult and immensely agonizing and lifesapping years that I have yet endured.
I am dubious, based on my nearly photographic memory of the near entirety of our relationship, such as sometimes reducing even down to the level of typically verbatim specificity the precise inflection, cadence, tone, and volume of specific conversations all the way back to our introduction, not to leave aside a very vivid recollection of the time of day, (such as: the ambient light thereof, the appearance the the effects of the season upon the local visible fauna such as fall leaves and their colors present, perhaps also how strong the breeze was that particular day, what the wind smelled like and from what direction it was blowing, or a long littany of other extraneous details even I am often very surprised myself to recall), based upon many of the periodic patterns of her behavior, the company she kept, the usual time of day some later numerous occasions of coincidental inability to answer the phone even at a pretty ordinary time for us to talk, the range and frequency of her excuses, my occupation which required frequent long absence to complete work and support the family and keep our attempted budget calculated a couple to a few weeks in advance with usually fairly reasonable accuracy, the frequency and durations of these sudden but almost cyclical absences or clusters of them, the previous record and body count of her marital infidelity in her previous marriage almost immediately before I entered the picture in her life. I can think of many troubling occasions past throughout all that soan of time that have the distinct probability of matching detail(s) one should expect in the case of a very beautiful but also much more insecure female narcissist with what I would think is possible passive aggression, inferiority issues, low self esteem in regards to romantic relationship and/or pracrical or perdormace

I guess it's not that common, but it happens. Life doesn't end if you have a kid as a teenager. You just grow up to be that person with a son that looks like he could be your brother.

I'm not shocked. Growing up, I lived in ghetto areas and I remember seeing pregnant girls in middle school and in high school. Some of the boys impregnated more than one girl. A lot of them would drop out of school once the babies were born.
