i'm stuck i can't breed some of my pokemon and i can't get family time to work am i doing something wrong or am i missing an item or is there a way to increase my pokemon's affection?
Only certain pokemon are breedable and those ones are found during the storyline or from quests. Most of the time you'll get into battles with them and they'll be uncatchable so you'll have to defeat them. After the fight you'll drag them back to your house's basement where the "training" will begin.
You'll have to purchase a whip, paddle, or crop from the mudkip merchant in your bedroom as well as some pokefood and then begin wearing them down with daily training sessions as their stamina allows, with the pokefood increasing their daily stamina, with them evolving and possibly demanding rematches sprinkled throughout. Once their resistance hits zero they become breedable.
