I can confirm this. I am playing on long lifespan. I did tummy time and all possible activities every single day and she started to crawl only 7 days before aging up. For me it is okay, i think it is kinda realistic that it takes time until she figures out everything. I agree with the patient part as well. These are infants. Be patient and practice every day. They will manage. ^.^ Oh and i don't know how much it influence the little ones speed of progression, but my infant has the "Intense" trait. 🙂
so what will happen to those who disabled the choice to age up? The infant will forever be in the state they can't crawl?
I only age my sims through forced interaction like cheats or the cake brithday.
I wanted her to learn to crawl before age up to toddler
