I just got Hearthfire tonight.I tried to put the child's room in Breezehome but no luck.I did a little research and I guess there's a problem with it(surprise,surprise) so I was wondering if anybody tried to put the room in Honeyside?The only reason I'm doing this is because one of the orphans,I think the one from Windhelm glitches,or so I read,if you don't move her into one of the original houses first.I know there is a patch but I have Real Life Skyrim and I guess they don't like each other.

As an Xbox 360 player I have had no trouble putting children's rooms in the original homes and have always moved the family to one of the Hearthfire homes first. Both my characters have adopted most orphans at one point, they all seemed the same. What problems you have because of incompatible mods and patches is not a problem with the DLC. You will just have to find out which mods are causing the problems and get rid of them.

Yes sophie the flower seller from WIndhelm can glitch, but I do not see how being over encumbered is related to moving her to a local house first, I have adopted her twice without problems, always moved her to a hew house, as a PC player you should be able to fix that problem, if it occurs.

I don't think it has anything to do with being overencumbered,I just remember reading something like you can adopt her but she won't show up in the hearthfire house unless she goes to one of the skyrim houses first.

Have you tried saving the game, then adopting her, then reloading if it doesn't work? There may not be a problem. Or, it may be intermittent, and reloading will fix it.
