Why does the baby put its hand in its mouth?
When a baby puts its hand in its mouth, parents almost always have one reflex: there's definitely a tooth coming. If I wanted to live from hand to mouth (not in the original sense, of course), I would have realised my brilliant idea long ago - and invented the so-called dentiometer for the U4 examination.
My plan: to make a device that resembles a Geiger counter. And when the children come to me at U4, i.e. when they are three or four months old, I run the device over their mouths, make a funny noise and tell their parents: "It will be another six, eight, maybe even ten weeks before a tooth breaks through at this point."
What makes me think that? Because I'm asked at every U4: "Don't you think there will be teeth coming soon because our baby is putting his hand in his mouth so much and he's drooling so much?"
The fact is that most babies don't get their first tooth until they are six to eight months old. And children don't put their hand in their mouth at four months because they are about to teethe - but because they can. In the weeks before that, the child is not yet able to coordinate its movements properly. But after three months it gets the hang of it:
a) My hand
b) My mouth
c) I can put my hand in my mouth.
And that's exactly why they do it so much and drool accordingly.
But in most cases it has nothing to do with teething. And if they don't believe me, then maybe I'll introduce the dentiometer examination for 20 euros an hour and predict the first tooth for parents. You know: in six, eight or ten weeks.

Stool examinations
One issue of increasing importance is unnecessary and often expensive faecal examinations. Very few very useful tests can be carried out with a stool sample. But it can also be used to do a whole lot of - to stay on topic - crap.
Bedwetting
When it comes to bedwetting, parents are often surprised by the point at which it is first mentioned. The good news is that if the child has been wetting the bed for a longer period of time, it's good news: It often only takes patience for the issue to resolve itself.
ADHD
Attention-deficit/hyperactivity disorder (ADHD). A long word that describes a complex topic. And a phenomenon that we still have to learn to deal with properly - not only paediatricians, but also society as a whole.
