This week, Alec Baldwin made a hurtful parenting mistake.

Given the divorce rate in the United States, as in Australia, stands at around 50 percent (and even higher for subsequent marriages), the concept of the “second family” is a pretty well-known one. Parents moving on to a new relationship and having more children is common, and while you’d hope that this mostly results in one big, messy-yet-happy family, I’d bet my lunch money a lot of first-marriage kids would disagree.

Particularly if their dad is a Hollywood megastar who has just forgotten their existence very publicly in front of more than half a million Instagram followers, as Ireland Basinger-Baldwin can attest to.

The 22-year-old fashion model and actress, born from dad Alec Baldwin’s first marriage to Kim Basinger, no doubt felt the sting when her dear old dad started posting pictures of his adorable four kids under five with current wife Hilaria Baldwin on Instagram. Captioning the pictures “one” for daughter Carmen, almost 5, and “two”, “three”, “four” for sons Rafael, Leo, and Romeo, Baldwin seemingly forgot that he in fact has five kids.

Oh. Dear.

The comments quickly erupted with fans reminding him that Carmen is actually his second daughter.

“Shouldn’t she be 2? You do have another daughter”, one commenter reminded him.

A less polite fan backed this up with, “Ireland is number 1, dumbass.”

After using the social media platform to (hopefully accidentally) insult his first child, it might make sense that she might make her feelings known in a similar way. Following Baldwin’s hurtful post, animal lover Ireland posted a photo of herself hugging an extremely cute little pig to her own followers, captioning it, “I go cry now”.

Is she sad because of the pig (this makes no sense; pigs don’t make people sad), or because of her dad’s thoughtlessness? Could it even be a cryptic reference to the infamous incident where Baldwin called a then-11-year-old Ireland a “rude, thoughtless little pig” via voicemail?

It took two days, and I would like to think a stern phone call, sarcastic text, or some good old-fashioned silent treatment from Ireland, for Baldwin to post a picture of his actual first child with the tail-between-the-legs caption, “actually, this is number one out of five…”

Actually, this is number one out of five…

Despite a rather nasty divorce from Basinger back in the early 2000s, his history of anger issues, and this most recent unfortunate dad brain-fart, the 30 Rock star and epic Donald Trump impersonator seems to enjoy a close relationship with his eldest daughter, regularly commenting on her often risqué Instagram pics in a good-natured and embarrassing dad kind of way.

For example, this photo she posted a few days ago, astride a motorbike in just cowboy boots and a bikini, and looking strikingly like her mother back in the 80s, which Baldwin responded to with, “No. Just…no.”

stay extra ????: @phatmango

Given his very fit yoga instructor and author wife, Hilaria, also likes to Instagram pictures of herself in underwear and bikinis (and good on her!), we can only assume it’s the motorbike he has a problem with. Those things are dangerous, especially without protective riding gear.

Let this be a warning to blended families and dads everywhere. Please don’t forget the children who came first, especially not publicly.
