With Utyun having had DKA in the past this puts him at greater risk of developing it again, especially if he is not getting enough insulin, not eating, stress, gets an infection. So it is a fine balance between him going to low with too much insulin and him not getting enough insulin and having that lead to another episode of DKA.
If your daughter were to see that Utyun was not eating his usual amount, appeared lethargic, just seemed to be sick in some way, it is important that she knows to take some action.
It is important to make your daughter aware of these signs/symptoms and to have a plan for what she should do if Utyun were to develop these.
Maybe if you have time you can right her a 'Utyun Manual' with instructions on what to do?
Maybe you can show her how to check for ketones?
Will she be in the house with Utyun? Or will Utyun be on his own most of the time?
Do you think Utyun will be stressed because you are not there?
By getting a urine sample, and using the ketostix. I think this would be a good idea, especially as she cannot monitor BG, being able to screen for these will be a very useful tool especially as she won't be monitoring BG.
We can always help her if she is able/willing to post here. So perhaps show her how to log on and post, just in case she needs help?
@Kris & Teasel am I right in thinking you or some other members speak japanese?? This might be helpful to Kaori's daughter.
Another option would of course be to get her to take him to the vet, if your daughter felt that something was wrong.
We should look at how he is doing by the end of tomorrow to see if the 0.25 dose is a good one for while you are in hospital. It is good he came back down into yellow.
