Something I've been gradually noticing over the years of playing with Sims 4 toddlers is that... I wish they were younger. Like in TS2 and 3. I know a lot of people prefer these older ones because ...
I guess I would prefer more progression in toddlers, like crawling and bottles until level 2 or 3 of movement skill, and cribs until they learn to walk, etc.... To be perfectly honest i don't spend much time on toddler and baby life stages so all in all I'm ok with things the way they are.
