maryeovinoRobin! You're back..and the timing coludn't have been better this morning! I was up really early this morning, FINALLY decided to clean up my blog and get back on my act plus I was reviewing some I have to take Lucy to the Endo this week, and have some questions for him. How are you? And Kate? You've started a blog!! I just read the first 2 entries I totally remember those feelings. I will read the rest by tonight. You are on Facebook? We should connect. I am under Mary Eovino.We are in a pretty good state. Summer has been interesting. I wonder what our Endo will say on Wed. Lucy's blood sugar numbers haven't been way out of whack, but I would say they've been higher than during the school year..don't know if that can be attributed to her sleeping in later and going to bed later, a little less strict diet, as we've been traveling so much..hard to say. She just got back from staying a week at Camp Merrick in MD that runs several diabetic camps for kids every summer. We went for an Open House in June, really just to check it out and see if it would be something we'd/she'd be interested in for next year. But we fell in love with the location (right on the Potomac River!) and the staff (mostly T1 themselves) and signed her up on the spot. It was one of the best things I think we could have done for her this summer, so that she could have fun with other T1 kids and gain a little confidence being away from us.I will be thinking of you all day today too Let's keep in touch

I find the pen much easier to carry around then the "regular" needle and vial. I have had the same results with the pen.
