Hi all, joeys are very close to being o.o.p -most days there's a little fist or two black tails popping out

I've read a lot of the info on here about joeys and breeding and just have a few q's in regard to the little ones:
1. I want to get some milk powder for "just in case" and was wondering what brands/types people would recommend?
2. Bedding wise what's best when joeys are about? I've got some fleece on the way which I was thinking of cutting up into fairly thick strips and using as bedding as it is now getting very chilly, and I'm not sure if it's a good idea to put my snugglesafe under their pouch (as I have been) in case it overheats the joeys
Mumma is crazily relaxed, she'll still lie on her back and let me stroke her tummy, and even cleans the joeys in front of me so I've got to see some little joey faces (EEEEEE
