Baby won't age up

[koriwaraa]

My sims' baby's birthday was 4 sim days ago and she still hasn't aged up, the birthday just moves to the next day on the calendar.

@koriwaraa have you tried clicking on the baby and selected age up or are you waiting for the baby to age up themselves.

@koriwaraa Try aging it up manually ( With a birthday cake/ clicking and selecting age up )
