Toddlers are soooooo annoying

I've learned to settle for toddler skills up to level 3 rather than aiming for 5. I always feed them by putting out a plate of leftovers. When I have twins I have them eat at the same time and play with toys close together because if they talk to each other they raise the communication skill. I always have a tablet for each toddler so they can keep out of trouble and keep gaining skills when the parents are busy. I always have the blocks set and when a parent has time I'll have them teach them blocks or play dolls with them. Sometimes I have the parents teach them to talk once or twice. Making the toddlers walk to their own food and then to a place to sit usually raises the movement skill pretty fast too, especially in houses with stairs (have to feed them every time they get halfway to empty though, otherwise their walking speed can put them in danger of being taken away for hunger failure). The parents always read them to sleep unless something's gone wrong and the parent's needs are too low, then I just have the toddler put themselves to bed. I play on normal lifespan and usually this gets them to 4 in every skill by their birthday without killing the parents.

My primary sim raised four sets of twins in a row so I developed a system. The household always revolves around the toddlers and no one else can have a social or love life because I'm too busy to deal with them, but usually I can keep everyone content at least. I'll have to keep some of @ChelleJo 's tips in mind going forward though, and see if I can eventually get one with maxed out skills.

Oh, but did you know if you hire a nanny you can play the toddlers at home while the parents go to work? They don't learn as fast by themselves but they can keep learning while the parents are gone so they don't have to use all the vacation days.
