I'm halfway into completing my dream home at Heljarchen Hall. It's my only Hearthfire home that I'm building so far. Just completed the family wing with the intention of adopting and making this my official base home. But haven't adopted any kids or hired any staff as of yet. I was fine with this plan until I discovered you can upgrade Breezehome in Whiterun with a children's room. Apparently you can adopt up to 2 children? So now I'm in a bit of a quandary.
I really want to take advantage of living in Heljarchen Hall, my large, beautiful--and most $$$$$---custom manor with the perfect family layout (family, kitchen & apothecary wings and all the outdoor support buildings). BUT
Unlike Breezehome, Heljarchen Hall will be vulnerable to Giant, vampires, bandits etc. attack since it's outside the protection of a walled city like Whiterun. So my family won't be safe

On the other hand, if I upgrade Breezehome, I'm going to lose my awesome baking oven, growing & making my own food, mill, farm, kitchen & fish hatchery, stables, garden, and all the amazing other wings in my Hearthfire mansion for the safe walls of Whiterun

So for those of you who have already built a Hearthfire home and adopted kids is it possible to:
1. Relocate them from a Hearthfire home into Breezehome? If so, will your spouse also relocate to Breezehome if you're married? OR
2. Is it possible to adopt MORE THAN 2 KIDS with the Hearthfire expansion? Has anyone tried to do this (without mods)? I read somewhere that there is a little girl in Whiterun who asks you to adopt her. Got this from the Elderscrolls Wikia site. So I'm speculating that this why the devs included the children's room upgrade for Breezehome with Hearthfire. Hmmm.
3. If you adopt the little girl in Whiterun and/or another child from the orphanage, wouldn't this mean you could technically adopt up to 4 children? Or even more with the other 2 remaining homes??
I wish the DLC included the option for us to upgrade ALL of the vanilla homes with children's rooms. I'd have given anything just to upgrade Proudspire or Hjerim with the option to adopt and raise a family there. Or more realistically, Hearthfire shoud've given us the option to build a wooden stockade wall around the new homes. These would be similar to the setup at the Orc encampments. A security wall that that with a lookout post would've gone a long way IMO.
Ah well. If I can't relocate my family to Whiterun after moving them into the new home, then I guess I'll have to use the Tundra Defense mod to setup some sort of garrison security outpost.
Raising your kids in the safety of a city hold just seems more fitting though
