It means Francis,13, who has the serious bone infection osteomyelitis, has to wait until Wednesday to go back to Tawfiq Hospital, Malindi, instead of going for an appointment today.
Once the leg brace, which will support his leg and hip, is ready he will undergo an operation to do a biopsy and to remove some dead bone.
The brace will be essential, as he will be non-weight bearing after surgery while the bone heals.
He will also be dependent on crutches, so Mama, who knows all about using crutches from her own past experience, has been giving him some lessons - much to the interest of all our kids!
On Saturday morning, Papa adjusted the crutches to suit Francis and then Mama talked him through using them - Francis laughing and smiling his way through and his the kids clapping him on!
He also joined Mama for today's video in which she gives us the latest update.
Francis has a long road ahead of him, and we have no idea how much all his medical treatment will add up - as there is no free healthcare in Kenya everything must be paid for and as we want to give this special young man the best chance of a full recovery we are using the best treatment available to us, which comes at a price.
We are so grateful to each and every one of you who has made a donation towards his care, we hope there may be others who would like to help. Any amount, no matter how small, will help get Francis back up and running like a 13 year old should be.
