A study at Columbia University (New York) has found that there is a higher instance of autism diagnosis in second children if they are born less than 2 years after their older siblings. This is in comparison to children who are spaced at least 3 years apart.
The study was done over a period of 10 years and researchers looked at parents of all ages to eliminate differences in age as a factor.
It is unknown why this occurs, but the researcher addresses two separate explanations for the occurance:
1. Parents are more like to notice a developmental problem because they have another child around the same age to compare the child to.
2. The mother's nurtients were depleted from the first pregnancy and were not adequate for a second pregnancy.
So, what do you think? Are parents just noticing differences in their children leading to a diagnosis? Or does having children that close together deplete vital nutrients and lead to autism in a second pregnancy?
