I think we have had many parallels over time and I guess this is one, also. My nearly 5 yr old son used to always get his meds at bedtime and in the last year our endo has pushed to give it as late as possible. Like OUR bedtime. This has been really hard as far as routine goes. His levels have not been bad....I think she is trying to get him to grow a bit more under the same dose he has now. I can't see any real difference. Did your endo give reasons for his/her reluctance?
