On today's blog, our Mama Sue talks about how lucky we are in the UK to have a national health service.
She's been backwards and forwards to hospital in Malindi with children who have been suffering a contagious skin infection.
Every trip has to be paid for, consultations and medication. Nothing is free.
Esther is the only one to still needs treatment and they are back at hospital with her again today.
Mama Sue always makes these trips into a happy adventure for the kids, so watch the video to find out why it was such a treat for little Esther!
