Random question but who is the oldest housewives’ kid?

Seeing Nicole have her baby, it made me realize that it feels like it’s been a while since a housewife had a baby. Last I remember I think Brandi from Dallas? Or that time when Porsha/Kenya/Eva were all having babies back to back felt like just a few years ago. I don’t really recall anyone having kids post show aside from Gretchen and former husbands like Paul Nassif and both California David dirtbags

Now I’m wondering, who is the oldest housewives kid? I can’t tell from google if Vicki’s kids are older than Jeana and Caroline’s.
