Did not know that photographs ups friendships like that. Good information!
Used the convivial, ley line lot traits.
Somehow, the original six kids all ended up with at least one of the following traits - paranoid, erratic, gloomy, loner, & hotheaded. Trying to get them to be friends was complicated. Spent the first day having the kids make friends and Bob & Eliza become soulmates to get them both fertility treatment. Moved the first out late Sunday/early Monday.
Used painting, the digital sketchpad to make money, also had the kids who had moved out in a club to keep painting (on easels) & clean. I also had a third club for kids inside the house that boosted painting and cooking.
When they joined households, the kids married their way out of the house (btw, the Pancake granddaughters are adorable).
I kept at least two kids in the house so that Eliza, Bob, and whichever two kids were there became good friends with the babies (which is very easy). As soon as a baby had four good friends, they were aged up to YA and sent to the kitchen to begin cooking (I gave them an extra stove for when one inevitably broke).
While twins are pretty much a given with lot traits & fertility, for whatever reason I could not get triplets. By the fourth pregnancy, I had nearly all the money I needed, so I bought the massage table, had Eliza get fertility massages before getting pregnant, during each trimester, and had her listening to kids music (even though that doesn't do anything). Still twins. The last three days were just waiting for the babies to be born.
