Add more milestones!

I absolutely love the new milestone feature that came with growing together, but it seems to me that they missed a few (a lot) of potential milestones when making the pack, like why isn't having a new sibling a major thing? Or buying a home? I hope that as time goes they could add more, building on the mechanics they've created. Things that are major events in anyone's life but just isn't a milestone in game.

Here is my list, but what is yours? Which milestones would you wish they'd added?

• Getting a sibling
  
• Getting a grandchild/niece/nephew
  
• Lost a parent/grandparent/child/sibling/loved one/friend
  
• Lost a pet

• Had a 5-star rated business

• Maxed a skill (one for each skill)
  
• First prom
  

Life/firsts:
