3 week old kitten constipated!

I have a 3 week old kitten, our cat.. Well.. every time she has kittens she pushes 1 away from rest wether they're sick or not. I've had this baby since the 14th and she's done great, her eyes are fully opened with no problems, gaining weight, peeing good..and eating well.. And all of a sudden she's constipated. Badly at that.. I've used a warm rag, cotton ball, q-tip almost every thing to help her. A vet visit is finically not possible and they won't give me any tips or home
Remedies over the phone what can I do to help her? PLEASE HElP!!

Are you bottle feeding her?  You can add a couple drops of olive oil or vegetable oil to the formula.  Or If not bottle feeding you can try and put a drop in the kittens mouth - the side in the cheek.  to see if that helps.

You can purchase infant glycerin suppositories at a pharmacy, shave off a tiny piece, and insert. You probably need to give the kitten extra mL's of water in between feedings as well.
