My son (3.5) always seems to cry or whine every time he's told no. I get that it's common and normal but in his case it feels excessive. I don't think he's ever just said "okay". Is there something I should be doing differently? I always tell him "I'm sorry you're upset" and then explain why the answer is no but then it doesn't stop and I end up having to just tell him to stop crying. Sometimes it feels fake and sometimes he's genuinely upset.
