This guide will show you how to get the Sit-Up milestone in (Growing Together) The Sims 4. First, you have to unlock other milestones to unlock this one.
Sit-Up milestone
Your infant sims cannot sit and they can’t do some activities if they don’t have the Sit Up milestone unlocked. You need to select your infant sim and tap on the Simology tab to find out if you have unlocked this milestone. Go to the Gross Motor category under Milestones and you will find this milestone there if you have unlocked it.
Unlock other milestones
You will need other sims to teach your infant how to sit to unlock this milestone. But there’s also another way to unlock it. First, you have to unlock other milestones (lift head, roll over to back, and roll over to tummy) under the Gross Motor category. So while controlling another sim, click on your infant and select the “Tummy Time Together” option. Now your sim will learn the basic moves.
After that, click the “Tummy Time Together” option multiple times to unlock the next one. You have to do this interaction multiple times so it will take some time. Once you have unlocked this milestone, “Practice Sitting” will appear.
Unlock sit-up milestone
You can unlock the sit-up milestone with this interaction. You have to tap on this option multiple times to unlock the milestone and then your infant can get fed using the high chair. You can also scoot and play with new objects. It will also unlock the fun need.
