"Distasteful paediatric appointment"

I attended a Paediatric appointment with my teenage child. I had my younger child and my toddler in tow.

The beginning of the appointment was ok, the paediatrician had spoken to my child about the outcome of the asthma trial they had undertaken. But then when the paediatrician started discussing my child’s background and what the current routine surrounding sleep etc. was, they proceeded to lecture both my teenage child and my younger child about their phone usage and screen time before bed. The paediatrician went so far as to say that their current routine/habits will shrink their brain. The paediatrician then started on my toddler, whom I had given my phone to so as to occupy them during the appointment, so they were not being disruptive; I recall stating that they have been on that phone since they walked in. My toddler is very talkative and would have made a nuisance of themselves and been disruptive had I not pre-empted keeping them occupied. The paediatrician then proceeded to try and prove their point about brain shrinkage by googling brain shrinkage and used an article on the affects Alzheimer’s has on your brain function as their argument. 

This paediatrician has never consulted my child before and has no idea about their history or their routines, bar from what they were told in those two minutes of conversation. I also point out that my child is a teenager and is not very good at communicating or explaining things.

I find it disgraceful that this paediatrician can use those two minutes of conversation as justification to lecture my children and in the same instance indirectly lecture me as their parent.
