Hmm... She does that thing where she will lick a rag to wipe away any dirt on her kids' faces.
She will also try to butt into her kids love lives. Not in a malicious or gross way, but she would see Dion or Frazie blushing around their crush ans then she would start asking them if they like that person, or if they want them to stay for dinner. She would also probably show their crush any baby photos in a way to show her how cute her kids were (and still are).
She's also pretty protective of her kids and very willing to through a fight for them. I don't know if that one is exactly a momcore one, but I do see her having to be held back by Dion and Frazie from fighting someone who said something mean about the family (Augustus is encouraging her and even ready to support her if she needs it).
