I have one now that is supposedly 6 weeks as well, but she refuses to do anything but syringe feed. I have found that using the large 12 cc syringes with the long narrow tips, are the best. They are mainly good because you don't have to stop and refill in between a screaming, starving baby!!! ;) I got mine at our local TSC (Tractor Supply Company). I am sure any local Feed & Seed or Farmer's Co-op store in your area would carry them. They are sold in packages without the needles!
GOOD LUCK, and don't give up ... you are doing a great job!
Hugs,
Kim ;)
