Well I'm gonna keep this simple as I believe face to face is much better for getting a good feel for a fit regarding a child.
But to sum me up, I'm basically a Viking that enjoys games, motorbikes and music. I am a large person so I do tend to find kneeling and speaking to a young person face to face much more effective when introducing myself to them.
I am a kind man and I do appreciate everyone is different and I may not be everyone's cup of tea but as far as I can tell, half of what makes a sitter a good fit is how a child interacts with them so I do encourage a couple of face to face chats, whether yourself and I or yourself and your child with me to voice any concerns or any criteria you would appreciate and would require before any bookings with myself could commence
