Don't you mind to ask you a question... Why you choose a Zoloft?
Another question, How will you feed your baby?
Do you research on a safe environment zone for your house? i.e. toxic things in your house such as old painting, plastic, air quality (both indoor and outdoor), chemical lawns, too much electromagnetic field (EMF) and a lot of list. This is where you find the closest possible what caused your baby's health. It's because a toxic in your baby has cleaned out that the lab can't find the problem.
