Everyone knows that anonymous letter writers are the lowest of the low.

But let’s for a moment put aside the bile and insecurity that practically jumps off the page of this particularly charmless missive.

At the heart of the issue is whether proud mums should litter their Facebook feeds with ten “hilarious” snaps of little Freddie pouring Petit Filous over his head.

Or curled up snugly in a White Company Babygro.

Or duck-waddling across the living room in that curious toddler gait that is so endearing to mums and dads the world over.

Are these daily updates acceptable in the nuanced world of online etiquette?

YES. Of course.

Why the hell not?

I’m surrounded by people who think exactly the opposite and their response to the anonymous letter this week has been some variation of “it’s a bit harsh but I see where they’re coming from” or “at last, someone’s said what everyone’s thinking”.

I’m baffled by this mentality.

Who are you to judge the appropriate amount of snaps a ‘friend’ should or shouldn’t post of their own kids on Facebook?

I don’t have children but my Facebook feed – like everyone else’s – is frequently inundated with baby pics. Some are sweet, some are funny and some are ‘meh’.

But I’m never going to begrudge someone for posting them. And if I did I could always block their news feed or unfollow, just as any of these moaners could. And I honestly couldn’t give a toss about the security; that’s for parents to decide.

That a storm of opinion can be prompted by such an innocuous matter surely means more complex feelings are at play.

Part of it undoubtedly plays into the lifestyle gulf between those who have kids and those who don’t.

Maybe that world of sleepless nights, baby sick and sore boobs is so alien to childless people that they feel freaked out by daily reminders of it. Or they can’t have kids, or aren’t interested in them, so the photos naturally grate.

But I’m not totally sold on this argument since a lot of people complaining about the oversharing are parents themselves (including the author of the original letter).

In this case, I wonder whether there’s a kind of petty small-mindedness at large that – from what my friends with kids tell me – subtly imbues itself at the school gates, or any situation where parenting is called into question.

Either way, I think we SHOULD be honest with ourselves: not about how we feel when it comes to oversharing baby photos, but where these feelings come from.

If a few hundred baby photos make you foam at the mouth, you have to ask yourself why the overreaction – and, as Oprah would say - are you really being “your best self”?
