My point is that children change. Don’t stop her looking at Medicine, saying she wants to be a doctor etc... but don’t make it her identity already. Praise any other interests she has the same way you would with biology/science/maths.
Maybe she will be a doctor, maybe she won’t. She shouldn't either be pushed or stirred away from it.
This very much so.
When my (now adult) DD was young ( about your DD's age or even younger) she made her mind up she wanted to be a doctor. We didn't take it all that seriously at that age because children change and also we knew that it was a very difficult path to follow and there was no way of knowing at that stage whether she would be able to get the academic qualifications.
Obviously we didn't discourage her but we tried not to put too much weight on it.
However, as she got older and started to move up through senior school she was still sure that was what she wanted , she was also doing very well academically and seemed particularly good at sciences. We thought well maybe there is something in this. When they had to do work experience in Y10 or Y11 she used her own initiative to apply for and get a w/e place in the local hospital.
Anyway I began to look around to see if there was other resources and support she would need to help her in to this career path. For example, I found out (probably through mumsnet !) that she would have to get a considerable amount of relevant w/e before she even applied and also about the aptitude tests (BMAT? forget now) etc.
So she started in VI form doing relevant A-levels and, we assumed still all keen on medicine. It was about half way through lower VIth, roughly when she was starting to look at University admissions, that she eventually said that she was having doubts. That she had realised she was interested in the science side of medicine but was not sure she actually wanted to be a doctor. Then it turned out that she had felt like that for a while but hadn't wanted to say because she thought we would be disappointed! Not the case at all - in fact if anything I was slightly relieved. Turns out my efforts to "help" and seek out potentially useful information had com across as me being really keen for her to go in to that career. I felt awful that I had unwittingly come across as pressuring her.
Well it all came good in the end. She applied for and got on to a degree course that was more in line with her actual interests and is now doing a career she enjoys.
So - long way to go from 9 yo to doctor. Don't read too much in to it yet!
