Question: how long are sims pregnant for?
Answer: After completing the 'A Bump-y Ride' quest, you will be able to select the 'Pregnancy' option from a crib. This will give your chosen Sim a 6 day long Pregnancy, but with no tasks to complete. Your Sims won't be able to earn Maternity Tokens during a 'Pregnancy'. You can also 'Add A Baby' to a crib.
