weaned (sp) too early

i rescued a kitten at 3-4wks of age. apparently her mother died since
she was an outdoor cat. i posted earlier about her liking to bite.
....it's starting to hurt...

anyway...i bottle-fed her for a month... until she started ripping
through every nipple i gave her. she seemed to want more milk inside of
her than she could consume through a bottle.

she's 9wks now and is perfect (- the biting). one thing that concerns
me is that i always wake up to her sucking the blankets that are close
to my body. the blanket is wet to the touch in many areas she has
attempted to get milk out of. this makes me so sad i want to cry. poor
thing. i just hold her and give her lots of love until one of us falls
asleep again.

is there anything else i could do?

....what about giving her a bottle when she does this...
....or is she too old for this?...
