I have a question. The child had a full examination in one year (ultrasound was not done). When they turned two, the pediatrician asked when they would be examined. I was told that all doctors will be going through them when they go to kindergarten. But it's almost three years now, and we still haven't gotten a place at the kindergarten. What should I do? If the doctor tells me again that there is an examination before kindergarten, he can wait until school, but already consider two years without specialists' examinations and blood analysis.
