high readings during the night.

You may well have to ask your daughter if for one night she could go without the supper so that you can do a fasting test.....perhaps let her have it in the afternoon instead??? I know-not the same...

It could be that her bolus really does need adjusting. I got told by my consultant that if high/low 2-3 hours after a bolus...first thing to look at is the carb ratio....and this for me, is almost double for my evening meals.....to that of my afternoon ones....

Hope others will come along with some ideas too...

This rise could be down to a few things.

It might just be that her body has gone through some changes and at that time of the day her insulin requirements are greater. This might be resolved by giving a bigger bolus with supper.

It might be down to her basal being wrong and the rise is due to the background insulin rather than the bolus given at supper time.

It could be down to the food given at tea being slowly digested. For instance pasta and pizza are very slow at releasing their carbs which can make bgs spike several hours later.

You might have to start doing some night time checks to see what her bg is doing through the night. Perhaps tonight you could give a carb free supper something like a sugar free jelly and some cheese. If her bg has then risen a few hours later this will probably indicate a need to increase the basal.

Hope this gives you a few ideas. May be some other people will be along later to add their thoughts too.
