(I am not using gender terms for frisk, so be prepared for there and they instead of she or he.)

(POV Toriel) Everyone was  starting to arrive, Papyrus and his family first because they still lived in the underground, then Alphys and her family, finally Sans and his family. "So good to see you again Sans, what makes a Skeleton smile?" Sans smiled brightly, " You tickle his funny bone, nice to see you again Tori, Grillby you know but I'd like you to meet Ash." Sans handed me a small red skeleton, "Careful, she's hot." Papyrus walked over. "Sans, the puns, you shouldn't influence your daughter, it will rub off on her." Papyrus said this with a smile I noticed.

    (POV Frisk) Frisk hadn't seen everyone in the same place since Asriel destroyed the barrier. He had been having a hard time adjusting and dealing with what he did as Flowey, but he was getting better. Frisk loved there adopted family and was overly excited to see all the new children of some of there closest friends. Box Mettaton was pushing a twin stroller with two very different looking skeleton hybrids that Frisk had met a few months earlier, Toriel was talking to Sans and she was holding a red skeleton, and Alphys was pushing an aquatic stroller with an infant aquatic lizard. 

   (POV Asgore) "Asriel, Frisk, can you come here for a moment," I asked, they both came when I beckoned. "What is it Father?" Frisk signed with there hands and Asriel asked,"Are we in trouble?" Poor Asriel, always assuming the worst. "No my children, nothing is wrong, just the adults are going out to supper and everyone is so busy that I could not get a babysitter, I was hoping you two could take care of them for a few hours, you are both around eleven, that seems about the right age." I thought Frisk looked a little disappointed but Asriel looked happy. "Don't worry dad, you can count on me and Frisk."
