Legacy Challenges

I read that the Sims Team is asking for feedback on Discord about legacy challenges but I can't access my account right now so I'm submitting here in hopes they see it.

There's three things that immediately come to mind that would made all legacy challenges a lot more interesting/fun

• Fix the infants. I haven't been able to do a 100 baby challenge since infants were introduced as having more than one infant in the house with other dependent life stages (newborn, infant, toddler) is a nightmare. The parents Sim glitches out and can't care for any of the dependents.
• Add pre-teens. We have three life stages for 0-6 years old, I'd like to have three for 7-17 years old too. Pre-teens would be a fantastic addition to the Sims, especially for legacy gameplay. It would ideally be ages 10-13.
• More activities for elders. Elders are pretty heavily forgotten, I'd like more stuff for them so legacy gameplay could continue in elder years with the same level of entertainment.

Thanks for taking the time to read my thoughts. I've got more ideas but these are the main that I've wanted for a long time now as a legacy gamer
