Sims mobile: babies

[JemGed]

Hi I have recently got a baby in the mobile game and I have a couple questions that if anyone could answer I would appreciate!:

1) How do babies age up in sims mobile?

2) After a newborn ages up is it able to use a high chair?

3) When can a child do a family event and how do you them?

Thanks so much!

For question #1, I would suggest you to watch this video by @rachybop 

#2 There are no high chairs on Sims Mobile. 

#3 Family events:

There is a limit of 3 events in total for babies, toddlers, children or elders per day. Every day a bubble will randomly appear on top of max. 3 your Sims (given they are babies, toddlers, children or elder). You tap the bubble, and the option to have a family event will appear.
