M.P.
I wrote several paragraphs and they"re gone. I agree with starting over with a different nurse not only because this one is frustrated but also to break the pattern.that's developed.
I suggest.you find a way to let go of the frustration and turn this into as much of a positive experience as possible.
Talk with him saying we're starting over. Tell him that you know he can calm himself. Tell him you'll use a therapeutic hold to help him get calm. Ask him how he feels about the shots and how you can help him get through the shots. Make him a part of the solution.
A therapeutic hold: hold him on your lap with him facing forward, cross his arms in front of him with you holding his hands, wrists or arms. Hold his left arm with your right on. Hold tightly. Cross your legs over his. Be calm. Say positive things to him in a helpful voice. Be sympathetic. "Shush, Shu shu, hold still, I know it hurts, this will be over quickly. You're such a brave boy. I know you're scared." etc.
I suggest practising the hold with him before using it to get the shot. Make practice a game. Be silly, have fun. Say, "I know we can do this."
Perhaps have him help tell a story about a boy who has to do a difficult thing. Perhaps draw picture and make it into a booklet. Make telling a story fun. Perhaps all of you make a story at the dinner table. Perhaps ask him to tell others his story. Perhaps include the steps to get a shot a part.of a story. Ask him what you could do to help him. Make him a part of the solution. Talk about his feelings. Give him an outlet to express him. Have him run, run, run, before or after the shot. Perhaps have him hit a pillow while saying such things as I hate getting a shot! I'm so angry. Let him decide what to say.
Read books together in which the character does a difficult thing.
Give him as many choices as possible. Right or left arm? Pick a shirt to be your shot shirt. If possible, let him decide when to have the shot. Let him be powerful as much as possible.
I suggest reading How to Talk so Children will Hear and How to Listen so Children will Talk by Adele Faber and ?
Both of you may benefit from a few sessions with a children's therapist. If possible, find one that specializes in health issues. A therapist may help you with the therapeutic hold.
Be firm in a kind way. Make positive statements. Once you get the shot,.you can have ice cream. I love to watch.you play and I want you to be safe, playing. You're the mom. Don't fight with him verbally or physically. You may need to "fight" to get him in a hold. Act as if you know he can do it. Fake it til you make it. No comments about past behaviour. If he runs off, wait patiently until he comes back. If he doesn't, go to get him. Stand patiently until he walks himself out or give the shot there.
