My dd was on NPH for about six months. My thoughts are that for US, it was great for about a month and I liked it for the transition. To help dd get used to shots (the nurse in the hospital said she was about the worst she had seen as far as fear of shots), to held us get a plan in place in a school that had no nurses at all etc. It worked pretty well for that short time. But after about a month she was fine with shots, was starting to fight us over the scheduled times/amounts and we needed more flexibility. However the endo she saw then was big on reducing shots for the kids, especially at school. It took us another five months to convince him to switch her. I do think it has it's place. Just a very limited one lol.
