Pediatrics or Paediatrics - US and UK spelling

It's not surprising that spelling of medical terms is confusing. Pediatrics is the US spelling, while Paediatrics is the British (UK) spelling!

In the answers to the questions on baby and toddler health, I use the US spelling for convenience. But in my usual practice, I usually use UK English so I say paediatrics and I call myself a paediatrician.

Most of the time, it's easy to figure out what the alternative is, but I have included this page on my site, so it's easy for you.

So, if you see a word on the site and want to know the UK equivalent, go to the US to UK Spelling section.

If you use UK spelling and want to check how I would have spelt the word on this site, go to the UK to US Spelling section.

Thanks for your "straight to the point" advice! I am very happy that you decided to add your wisdom to the internet for all to read. You made a very worrisome toddler's fever day into something a lot calmer.

Dear Dr.Maud, I had to write a thank you note for all the work you put into this site to make our life easier! We had many questions and worries but we found all the answers here very easily. You helped us to find a way to make our little boy eat again and calmed our worried minds when he was sick.. So much useful information, I recommend your website to all moms and dads I know. Thank you so much, you are fantastic! Have a wonderful day! :)

Thank you so much. I have taken ... to three different Dr.'s and you are the first to answer my questions in a manner that I can understand. You explained everything in English for once, and told me things that none of the other Dr.'s did. Thank you again. I really appreciate your help.
