About This Mod
The Let Friends Age Up is an essential mod for teen Sims living on the same lot. It allows you to age up NPCs as your teen ages via the Cake option in the pie menu. This way, your teen will have more Sims their age with whom to interact and play. You can select up to 20 Sims to age simultaneously. Just ensure all the Sims are on the same lot.
