My kids' former daycare pushed for an ADHD diagnosis and medication for my then-3 1/2 year old daughter, they even tried to get child services involved. Two other chidlren, one her age and one younger but I'm not sure quite how old, at that daycare were already on Ritalin. They also claimed her twin brother was autistic because of a tactile sensitivity. I won easily and switched daycares - immediately. Believe me, it happens.
Damn, sounds like those people were ijits...
I wasn't so polite.
good for you!
