John, if you want a Glider clamped on to your nipple that's your business!

Personally, I will stick with the warming pouch. In order to rehydrate them and get food in to them you need to bring them round, the longer it takes the harder it is going to be to get them to take anything. Once they have warmed up they can be persuaded to take fluids. The suggie's blood sugars drop so low they need a kick start and it's important to get them warm ASAP. As I said, the heating pouch allows you to warm the glider and keep them warm while you are getting fluids and food in to them and I have had 100% success rate using this method.
I have had a glider that was that deep in to torpor it took 2 hours to bring her back to the stage where she could eat, seriously, I thought she was dead and I was about to wrap her up and put her in the freezer when I saw slight movement of the ear. Had she have been 'down' any longer - or had I not have warmed her enough ASAP to start the rehydration process I would not have had a glider!
