We invited kids to ask their medical questions and here are the answers.

From why we need vaccines to how germs get into our bodies, what the heck an appendix is and the big one, why needles hurt.

Dr Preeya has all of the easy to understand answers for these very clever questions.

Joining Preeya to ask the questions (and give one or two answers) is her daughter "Stevie".

This is a great episode for the school holidays, a long drive or just passing the time at home.

If you need some food ideas for the festive season or just a solid laugh and some banter - this one is for you.
