One dad's approach to getting his wife in the mood.

We know almost everything changes after you have a baby. But for one dad, the most notable change has been in his sex life.

Or… lack of.

So he’s found an awesome (slightly passive aggressive approach) to addressing the issue with his partner.

He has spelled it out for her. Literally. In alphabet tiles.

In case you can't see it, it reads, "Mom fuck Pa 2 night sxy bed."

How romantic.

No word yet on how his partner took to the message, but it has been viewed almost two million times on Imgur.

You can probably understand why.

All we can say is, it's lucky their baby can't read yet.

Watch the video below for The Mum Code. This dad obviously didn't get it...
