Any Tips for mom of 5yr old just diagnosed type 1 diabetes ?

Does anyone have some tips I can give my SIL,  her 5 yr old son was just diagnosed with type 1 diabetes and she doesn't know how she is going to be able to check his blood sugar and give him injections everyday without him screaming and crying. He is a very energetic kid and very smart she said he is so afraid of needles too.
