with a doctor's stamp?
Doctors are completely bad at this, they don't pay any attention. In response to complaints, the management throws up its hands - "war, there are no other doctors and there will not be"
... and physical education lessons in particular.
The pediatrician simply wants to write out a certificate without going through doctors and without passing tests.
Do I have the right to ask the pediatrician to send the child for a full examination? pass the commission, maybe some tests should be passed, other doctors should be visited?
