I drop off my children at school everyday - BUT - one morning I had an appt and my father-in-law dropped my youngest at nursery school for the first time.
She was crying and didn't want him to leave. I felt so bad because she normally doesn't do that when I drop her off. She is also 3 years old - and still so little.

Just wondering - do your children get emotional when another caregiver takes them to school (someone that normally doesn't do it everyday?)
