My ideas for new expansion packs.

More stuff for babies infants and tots. Buggies and strollers to take them on walks a bouncy seat for infants and a walker that is able to use once the infant can hold his head up. Cars and the ability to teach teens to drive. car seats for newborns infants and tots that can be put in and removed from the car. Booster seats for cars for children too. a hospital related pack or items. Surgeries for sims broken bones able to wear a cast of your choice of color and walking boots for broken foot ankle. More birthing options without a mod and options for family and friends to visit mother and baby. Add items for disabled people or crutches for broken leg, foot, ankle. (Items can include wheelchairs canes for elderly. A school expansion pack, not just for high school but for elementary too and options to follow children to school. School options, in person online homeschool military school for the troublemakers and boarding school for the really smart kids. A military expansion pack where family members can go overseas for like a year and fight in a war, but will they come back safe? Families at home can e-mail call their loved one and meet them at the bus when they come home. An Amusement park would be awesome too where sims can find out / choose their thrill level. Ex loves rollercoasters and thrill rides, or they get sick or scared on them. A nursing home for elderly to go into if family should choose that and visits them. I know it's a lot of ideas, but I'll puts them in order of importance.

1. Cars and teaching teens to drive and car seats for the cars Mechanical skill for fixing cars, garage doors (can be used as a game update)
2. hospital stuff
3. school stuff (follow children, more school options)
4. amusement park
5. military
6. more baby tot items (can be used in a game update
7. nursing home (can be used as a game update but add wheelchairs and canes with it)
