my neice was diagnosed with type 1 sept 2007. tally, my neice went on a pump last october. we tried every pump pack available, nothing kept up with this 9 year olds energy level. pump kept falling out. my sister made her own pack....after many different tries tallygear was born. anyone using a pump needs to try this pack.....it has helped her live a more normal life.....www.tallygear.com..........life is fun..
