Re: Tamperproof receptacles
No they are not required by the NEC.
I have done one childcare facility and tamper proof outlets where required by specification.
You will also find GFCIs are not required except in the bathrooms and kitchen.
The place I did had many sinks for changing diapers with outlets right next to them, these where shown as normal outlets
We used GFCIs for these along with child safety caps.
