Remember back in the early days of Facebook when updates were mostly
just pictures of you and your single friends having a blast? Nowadays,
the only photos you seem to be getting on your newsfeed are pics of
their kids.
The fact is that many kids born today will have their
parents to thank for posting every aspect of their on social networks.
As for the rest of us childless folks, that means having to deal with
posts such as...
I'm Pregnant!

This is basically how it all starts. You'll receive weekly updates on her steadily growing fetus, and will soon become more familiar with their ever-growing belly than you will with her face.
My baby is born!

You won't have to pay a visit once the bundle of joy is born as the proud parents will probably be livestreaming the whole event from the delivery room. And don't be surprised if they also hired a 'birth photographer' to capture pictures of the baby crowning (warning, link is Not Safe For Life!)
My baby did this cute thing

The life of a parent is full of surprises! Unfortunately, every surprise they uncover usually means having to share it with the rest of their social circle so that they can all talk about it during the next meetup.
You should try having a baby!

Once their baby is no longer big news, parents will sometime try to 'mommyjack' other online discussions by complaining how us child-free folks have it way too easy.
My baby is my everything

At this point, the friend you once knew is no longer your friend but a shadow of their former self. The only way the know how to respond anything is to relate it to babies. Guess that's what happens when you've been sleep deprived for so long.
Why did I have a baby?

This is the realistic parent who acknowledges that while having a kid is great, it's really not all that it's cracked out to be. But at least there's one thing to look forward to: free booze!
