Transferring Child's Medical Records from the US

Has anyone done this? Is it straightforward? My daughter doesn't have any allergies or significant medical history that her GP would need to know about, but I do want to make sure that her immunization records transfer.

Has anyone had problems transferring medical records from the US to the UK?

For my records I just called my US doctor and had a copy made of all my records and brought them with me and presented them to my GP when I went to my first appointment.

I did exactly the same thing for my own records (don't have kids).  The GP didn't want all the records but he did want my immunization records.  I think I had to pay my US doctor to get the records since I was picking them up and they weren't being sent directly to another doctor but it wasn't much and was definitely worth it as a couple specialists have requested my previous medical records.  So, I would suggest getting your own records in addition to your child's records.  

Boo.

How did I forget to make copies of these before leaving the US? I might be able to convince them to fax the immunization record over, but I don't know if they'll be willing to pay the long-distance fees. I'll see what I can do.
