full house

Hello! I married Haley and had both kids. They are even both fully grown now. This was about a week ago real time and over a year in game time. My achievement for completing this has still not unlocked. I've done some research and there's not much info on this achievement being bugged on xbox...

We had our second baby born (boy #2) and we didn't get the Full House achievement unlocked on my Steam profile. In case it is relevant, the first baby appeared in the upgraded farmhand cabin, and the second baby appeared in the main house.

I already have two kids,but I didn't have "full house". WHYYYY？？？Today, I done this again,still not.
