How do you adopt a child in sims 3 ambitions?

Click on the phone, click Services and then click Adoption.

They social services come round a few minutes (our time) after you make the call and they give you a choice of male or female and baby toddler or child it is pretty easy and you can adopt as many as you like in one day!!! =)

But You can only have up to 8 family members so you cant have as many as you would like!!! Just Sayin
