Changes Sims 4 should make

i completely agree with you and speaking of toddlers, i shared my ideas which is based on toddlers and more activities to do is one of them Can we have a toddler based pack? | EA Forums - 12111749 

an another change in my opinion is a home schooling pack for both children and teenagers (and preteen if they get added too)

Well I've been wanting a Preteen Lifestage since the Sims 2 (I feel like a broken record.) I've been repeating myself for over a decade now about Preteens Lifestage being introduced to the Sims franchise. 

What I would like for Preteens is a middle school y'all remember the rainbow core cas that lost to the goth core well bring it back with Preteens pack but not just for Preteens all the life stages can wear the rainbow core CAS I'm talking from newborn all the way to elder. 

Preteens go to middle school it could be just like the rabbit hole school because HSY is too buggy and limited for me but I do want to do a winter fling and end of school dance, first crush like in Sims 3 we had a pink heart it can work like HSY but you can see they really get flustered, they can go on chaperone dates, hold hands, kiss on cheek, share the love struck candy, ride the rides in copperdale together. 

Voice crack moodlets like the voice will crack when talking especially the boys, girls will know that they developed a little more so they check themselves out in the mirror either they will like it or not they will become more moodier probably more moodier then the teens they can ask their parents or older siblings why is the body changing. At this age they can see what they like or dislike with the skills like do they like painting or crafts in general, or do they like exercise, they can do basic cooking or join their parents to learn how to cook. 

Also style wise some Preteens may not like the rainbow core maybe they want to wear black, blue, yellow, some thing punk, wearing light make up, wearing jewelry.

Also still play void critters, play or hang out on the playground and treehouse, play marbles, hopscotch, play or hang on the monkey bars, the swings like they did in Sims 3. 

"Borrow older siblings stuff." Door slamming when they are moody, talk back to parents, older siblings, any authority. 

I don't know about asking about woohoo to be honest since they are still young you know.
