School Aid Needed For 1 Child In Riverside

I'm looking for a caregiver a. k. a. Aid for my son School. He goes to a catholic private school in riverside. He does have a delay due to being premature. In order for him to attend a private school he hast to have his own Aid to assist in anything he might need for example going over work that his teacher has taught, and he may not fully understand and go over other schoolwork he may need help with and also the physical aspect. Also must be comfortable changing diaper when needed. Assistance with lunch if needed as well but overall the academic part is really important to help him at school.
