I can think of some positives:
The pediatrician lets me call him at home.
I make time to go on every field trip.
I get to talk to the principal, school nurse and teachers more.
I bring healthy snacks wherever we go.
I could justify getting a phone with internet service (restaurant websites often have allergy info.)
My daughter is extremely responsible and thinks ahead.
Her friends care about her A LOT and look out for her.
My daughter (almost in middle school) still likes having me around.
And my daughter's big excitement... when she starts riding the bus she'll get a cell phone! Awesome!
