Individual Attention

• Most preschools have multiple children per class, and the teacher may not have the ability to give each child the individual attention they may need or want. The National Association for the Education of Young Children recommends a teacher to child ratio of one to 10, but that is not always the case. Early childhood programs are designed to teach children basic education as a group, and not necessarily on a one-on-one level. Lack of attention may cause a child to act out or not learn as effectively as she would with more attention.
  
  

Exposure to Illness

• Your child will be playing in a classroom with potentially sick children, sitting within close proximity and sharing classroom materials; therefore, exposure to illness is likely. The Centers for Disease Control and Prevention says that bacteria can live on any surface for at least two hours, leaving your kid vulnerable to viruses. Although it is expected that parents will keep children at home while they are sick, it is not guaranteed. Your child may get sick more often at preschool than he would if he were to stay at home, being cared for by a friend or family member.
  
  

Lack of Quality Time with Parents

• Preschool children can spend as much as nine hours per day in school and have minimal time to spend with family once they come home at the end of the day. Young children are usually in bed by 7 p.m., and school can end as late as 4 p.m., leaving just three hours for dinner, bath time, story time and family time. The lack of time cannot allow parents to give the child the quality one-on-one time he may not have received while in school throughout the day.
  
  

Potty Training

• Most preschools require your child to be potty trained prior to entering the classroom; that means she must be wearing underwear and not diapers. This can cause issues if your child is recently potty trained because the probability of accidents occurring during the day is greater. If you're trying to potty train your child in time for preschool and it is not happening, it may be best to wait until you feel confident in your child's potty training abilities prior to sending her to preschool.
