In our case we look for the perfect combination of functionality and style! Because in that little beauty we carry: meter, lancing device and replacement lancets, test strips, glucose tablets AND a protein snack, all supplies necessary to change her insulin pump site (IV prep pad, alcohol swab, insulin cartridge, infusion set, and insulin bottle), emergency glucagon kit, replacement batteries for the pump AND meter, and a syringe. WHEW! Bet you would think this thing would be bulging, huh? But it isn't so! And it really isn't that heavy either! All in the organization!
(Please know I do not work for or represent Amazon or the company that sells this scale - nor did I receive the scale for free) But this is the scale I found and we love it - Digital Nutrition Food Scale. In fact, we found it so handy, we bought an extra one to give to the school district to aid them in determining carbs at school for our daughter and any other diabetic children at the school!
So, while I have considered taking the scale with me, I have drawn the line at doing this. I will take it with us on long trips away from home but it stays home for meals out. While I would love to KNOW what those carbs are in that meal at the restaurant, I am going to guess and fix it later because while we are open and honest with others about T1D in an effort to raise awareness, there is only so much stuff you can lug along with you. (...although I will admit to keeping a set of collapsible measuring cups in my car in a sealed baggie - for emergency purposes, of course! You never know!!!)
With the aid of the insulin pump and the continuous blood glucose monitor (CGM), we are able to fairly closely monitor those numbers and fix the highs and lows that result from the "guesses" we chuck at a restaurant meal. I suppose the hardest part is learning not to be so hard on ourselves.
