Without ketones in the picture, I agree with sue that skipping wouldn't be a bad idea. Until we can help you establish a safer starting dose. I don't do that.
@Bandit's Mom might be able to help with that and with your spreadsheet. It should open to a page with US numbers on it but it doesn't.
Have you set up a hypo kit yet? This sticky explains how:

You want to do this as a priority, so that if Mia goes into lower numbers, you have the tools you need to keep her safe. You always want to make sure you have plenty of test strips on hand, along with some honey/syrup and some medium carb and high carb foods. That way, you can bring her numbers up to a safe range if needed.
With the freestyle lite (human meter), the "take action" number is 2.7 (=50...we go by US numbers here). Meaning, you would feed Mia some carbs to get her above 50 and you would test every 30 minutes (every 20 minutes if using syrup) until you are certain she is going to stay above 50 and not drop back down again.
You shouldn't need to worry about this if you skip insulin today. But it is the most important information for you to have, for Mia's safety.
