At what age or what point would it be logical to test a child for learning disabilities? We are beginning to wonder about our 4-year-old. She is in her 2nd year of Montessori. The fact that I have one and at least 2 other extended family members have them makes me more aware of the possibility. The fact she is having trouble at school makes me wonder if it's more than just an age/maturity thing. Might be too early to tell - I don't know. Vision and hearing have been tested in the last 6 months and were fine.
