My wee man is 6 months and has his 17oh checked 3 monthly now , up to a montha go it was every 6 weeks, and he neded it adjusted  in reference to weight and height measurements. I have read that bloods should be assessed with this as well.

He also has his electrlytes and renin checked with the other hormones.

They adjust his meds up and down in relation to the 17oh and his growth .

So far we have has a dose adjustment about three times since his initial diagnosis.

Small changes , 0.25mg up or down as he needs it.

He is growing along the 25% line , and is really healthy.

Hope this is some help,
