If i remember correctly I think its a boy and a girl. There's a few chapters back where they're each referred as she and he. Honestly they look like girls to me too.

I thought they’re both girls?

Not a stupid question cuz in chap 36 they referred to one of them as the son but then when they were wearin uniforms both of them had on skorts/girl uniform and both are dressed the same in a lot of scenes

Just glad I'm not the only one. I thought the pink eyes child was a girl and the green eyes child was a boy but then they started dressing the same then they stopped addressing them but just saying their names.

I personally think purple eyes is a girl and green eyes is a boy, and they simply like dressing the two up cutely ^^ They usually wear the exact same outfits, with the color being the only difference.. But in chapter 34, Pinkie wore a dress, and Greenie wore a similar one but IG what you'd call a more masculine version, since instead of the same dress or a skirt, Greenie wore shorts. And the outfits they wore that were the same are nongendered ones >< Though I myself don't think clothes are gendered, looking at it thru society's pov, it could be an indicator that Greenie is a boy(Though, a very cute one)
