For my own curiosity, I'd like to compare ISF with other 8 pre-puberty year old girls with diabetes approx. 55lbs. 50inches. Is there a magical calculation for determining an ISF in children? I see a lot of calculations for adults, but they are post-puberty, and the calculation clearly doesn't work for kids. For example, our doctor told us for kids a good daily total basal rate is 0.5u/kg/day. It seemed correct for us. I just like to know if we are anywhere close to 'average'. I know everyone's different and it depends on activity, etc etc. But I'm just curious! I like to compare. Magical calculations. I'd like to have any.
