You will see little Sophie visiting the family and there is a birthday party and lots of imaginary friends running around following their owners. None have become real yet but they are about to start working on it. I see them as more potential partners for the rapidly growing young sims.
Petal gets the 'When Dreams Come True' opportunity - but I decide not to let her do it. She is going to learn the make the potion on the chemistry table.
At least 3 of the children have made best friends with their dolls and are going to work on the chemistry table. Two others seem to be happily working on their relationships with their dolls, and little Percy just got the message that will lead to that opportunity if he keeps up playing with his doll so happily.
Olivia and Don keep on going to work. What I really want from them is the One Kelvin Fridge. Haven't had a sim get one of them for many years and it used to be the first thing I went for in every game for years.
