At school infant care

I concur with all mommies. I've seen how some moms at my son's infant care keep blaming teachers for every little thing like even a scratch on the face when it's clearly that the boy's fingernails are long. I was at home with my boy in his first 9 months and even at home I can't stop him from falling, what more the teachers when they have to take care of a few babies. I bought a baby head protection pad for him to wear and the teacher said it helps alot.
