When you start Levemir, put a blank line in the spreadsheet after the last Lantus day, so we can easily see when you switched. Then label the line something like "start Levemir".
I agree with Elise, the best way to get regulation is to follow a dosing method. It looks like Aiden's dose is way too low. I have no idea why you reduced the dose. I rather suspect you've been getting some bad advice from a Facebook group. The spreadsheet you have is not our standard format and looks like the FB one. Levemir is not a magic bullet. I really liked Levemir when we switched, but my girl was in much better numbers at the time. In addition to following SLGS more closely, I would suggest posting here more often for dosing advice. We can help you learn what to do with SLGS.
