You have been married to an Echidna for a little over 10 years. The two of you have been astonishingly proliferate, having produced 24 daughters with more already visibly on their way.
It started with a pair of identical twin Echidnas. Soon after, the two of you had fraternal triplets. It was getting difficult to take care of all 5 of them when you both found out more were coming.
After beseeching the Demon Lord for help, your family relocated to the Royal Demon Realm, where a rotating team of babysitters and wet nurses help you care for your many children. Up until this point, there were no major complications.
About half a year ago, your wife gave birth to triplet Hellhounds. She's had only enough milk to regularly suckle two of them at a time, so the third was often tended to a holstar wet nurse.
About a month ago, one of your hellhound pups began to cry almost all the time, except when in the presence of this specific holstaur. On the nurse's day off, the poor thing refused to feed altogether, not even from her mother, until she returned the next day.
Not only that, but your firstborn twins have started to get particularly clingy with you. Whenever your wife was tending to the younger children or otherwise away, at least one if them was wrapped around you at any given time.
The scholar you inquired explained the Hellhounds' innately indomitable will. He also tells you that your firstborns are getting to the age when they instinctively start seeking husbands and that they've likely targeted you. You have yet to inform your wife, as you've just recieved this knowledge, yourself.
What do you do?
