I don't think that socializing with the toddler or baby or whatever your trying to age up will matter towards age but instead towards their personality. Babies take: 12-24 hours
Toddlers take: about 48 hours
Child takes: about 3 or 3 1/2

For me, the duration of the wait started to take longer, possibly.... 4-5 days at the max

To age my baby it to 3 hours. One of my sims had their toddler turn into a child... but I can’t find a pattern
