I had a sim mother with six toddlers. It wasn’t too bad after you give the toddlers the toys and tablets, and then take some chunks of time to potty train them, little by little.
Feeding them is easy: just cook a dish serving and put the dishes on a low table or on the floor. The toddlers can toddler over and just pick up their own serving. Bam, fed.
The toddlers can learn to walk and talk by themselves. All six of the toddlers learned to walk and talk by attempting and doing those actions by themselves (and talking with each other).
My goodness toddlers chatter so much, lol. :lol: Talk, talk, talk, blah, blah, blah.
ETA: To me, the Sims 4 toddlers are much more independent and easier than previous sims toddlers and real life toddlers, imho, lol.
And yes, the occasional nanny or neat sim to clean up the messes is quite helpful as well, of course, haha! :smiley:
