Growing Together Bonus Content
(from Pre-Ordering the Pack)

Those are custom versions of the bonus content that players could get for pre-ordering The Sims 4 Growing Together back in 2023.

Since there's no way to unlock the items, like with the rewards from live events, I've set it up so that if you put down a lot that contains one of the original items, but you're missing them, the game replaces them with my own custom ones as fallback objects. The custom version of the infant carrier needs an additional posture override to make them them show up instead of the original ones. Please let me know when they still aren't showing up for you. The needed tunings should be Base Game, but I don't have an option to test it properly, because I own the original carrier and I cannot make my game ignore it for testing purposes.
