Here are my notes for that part:
おいミカトすんな
oi mikato sunna (mikato is the baby's name? but it's a girl's name...)
oi, mikato, stop it (i'm going to omit the 'name' because it isn't confirmed anywhere else in the doujin)
"Oi, stop staring."
So.... Rin x Sousuke's kid might be a girl named "Mikato" (Mikato is a female given name). At one point in the doujin, Sousuke calls the child by that (p13, where the kid keeps staring at Rin, "oi, mikato, sunna~"), but because there are no other indications in the doujin that it is a girl, and because Mako x Haru's child is never called by name (also no indication of gender), I decided to leave that out. Just some extra info! (=・ω・=)
