Kinger and Queen parents

Korolev and Queenie are the parents of Pomni and Ragata (Ragata 10, Pomni 5) When Pomni was a couple of years old, she didn't want to drink milk at all, Koroler suggested Queenie feed her sandwiches and since then she hasn't eaten anything but sandwiches (even her first steps were towards the refrigerator), but Ragata was kinder and now goes to the 3rd grade...
