Honeymooning?

My son was diagnosed with Type I about 7 weeks ago.  He started on Lantus 15u and Novolog 1:12 ratio at meals.  His doses gradually declined as he entered the "honeymoon" phase.  He is very active and runs cross country.  Last week, his Lantus had to be discontinued completely because of lows and his insulin to carb ratio was changed to 1:50.  He is still having lows even though he is getting a total of 3u Novolog per day.  Has anyone else experienced a honeymoon phase like this?  The clinician in me knows this isn't going away but the mom in me hopes for a medical miracle!  I just read the article about MODY being misdiagnosed as Type I.  Thank you in advance for any input.
