Just saw this and really pleased you little one is fit and healthy now.
Can I use the opportunity to spam/raise awareness of a charity that helps with these kind of things?
Really REALLY easy to have a sample taken (spit in a tube) and have your details entered on a database. We got our whole regiment on within a morning. If a child being cured of cancer needs stem cells they check the database for a match. Stem cells are taken from the donor and transferred to the child to reinvigorate/aid recovery. Sorry I'm not a doc/medic, please see the link and get on the database:
