How do I keep her warm?

[Kazbah]

I don't know really - I just feel Pip's tummy to see if he's warm enough and he's usually toasty warm, just wearing a singlet. If he's not then I put on another shirt the next night ... They are good though, we also use them when taking him bushwalking in his bjorn, just add a beanie

ETA - these do have legs, they're like a bonds wondersuit but with zipper and feet and made of double layer polar fleece. The brand name is Snugtime
