Hover over it to get the details of the soon-to-be-born Sim! When they come back, you’ll find an Ultrasound Scan inside their Inventory.
It’s a Rabbit Hole visit, so your Pregnant Sim will be gone for about 60 to 90 in-game minutes. Like a real ultrasound, this visit will tell you the number of babies to expect and their gender. Littlemssam’s mod unlocks a Gynecologist that your pregnant Sims can visit during their 2 nd or 3 rd trimester for an Ultrasound Examination.
I happen to prefer the latter over the former, but even I found this mod cute and creative. Simmers who enjoy a very family-oriented style of play (as opposed to the “forever Young Adults living their best lives” style) will probably love this mod.
