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.
