Dude. He has made a decision to release the content so that we have something to play. Most likley we will get a small update in the new year to give us children or it will be part of the next big update.
He is a single Dev working in this basically by himself (he has a Tester & Animation guys but that's it) & a family. It's been christmas & new year, big family times. I rather he finished what the bulk now & gives us something than leave us wanting till the new year.
Also I agree with
Pdoan, if you are a paying patron then go complain there or else just accept it like the rest of us pirates.
