Baby wearing?

I wore my daughter at 3
Months old and used a carrier similar to this below. My ? Is for those who wear baby all the time or for special outings would this world for an infant? I'm nervous as we will be going to my daughters preschool once a week from birth till about 11
Weeks.  Should I never in something else? I have the money wrap
And never got the hang of it and it was extremely time consuming.
