The 5 most important things that you need NOW !

Vechiles for moving Sims in and out the house, parents dropping kids off to and from school, parents going to work, the school bus shows up, watching your neighbors leave or come home. It will feel realistic and lively. 

Both Preteens and Middle Aged Lifestage. Sims throughout the franchise kept missing the middle stages in life and they are the most important they finally recognized infants but that's because simmers kept complaining about the baby stuck in the bassinet. However Preteens and Middle Aged are also the middle ages that kids develop into a preteen they are older then a kid but younger then a preteen and they are going through changes the start of puberty like the voice cracks, they noticed that their body developed more and their more moodier because it's the early stages they don't know how to handle puberty yet. Middle Aged Lifestage it's the end of puberty they won't have kids, early retirement, have a senior discount, still be a fun grandparent can do things without over excursion like woohoo. 

Pacifiers and Strollers All 3 need pacifiers the newborns, infants and toddlers it look cute and it will soothe them so the parents don't have to keep doing it. Strollers for both infants and toddlers, The Sims are not pack mules stop putting everything on them we put everything in the inventory, they have to carry toddlers and put infants on their backs. Toddlers are so slow I get they are learning to walk but when we go places they are incredibly slow please we need strollers also it would be fun and cute and realistic to see families walking around the neighborhood with strollers.
