We've just come off school holidays and van's lantus needs went up drasticly. sInce June he's gone up 3 units a day to 16u. It seems like ahuge amount for a 9 year old 34kg boy. What are your kids on and can anyone remember the dose/age estimate? This seems like a huge hike and whilst he's obviously fighting off something at the moment (a spider bite from Tuesday I think because his forearm is like popeye) he's also getting 1.65u basal ph on the pump and it's not touching the numbers. Ketones are small o.2 but he's feeling rubbish. Any help with the ratio might help, it may be that we've under dosed him for a while and he's just catching up or that school burns off way more sugar with the mental stress because he's been as active as ever for the holidays. Cheers all.
