nope, although this is just my guess but that's not possible .the author just wanted to make this kind of kid with the parent like that. if their kid resemble them 100% then it's not fun anymore
I'm 90% sure it's a boy because of the conversation they had when doing the ultrasound earlier in the story. Plus, historically, male babies would wear dress like clothes, especially when they were super young.
I wish everyone would be as honest as he was begging of the ch but not as horny and kinky as him (●'◡'●)ノ there should be adjustment.
