How To Stimulate A Kitten To Suckle?

My kitten just turned 1 month old on the 20th of July. I have been feeding her with a wet food that is formulated for kittens all month and she has had no problems eating it. She is very playful, outgoing and social so far! I am wondering if anyone can give me some tips on how to stimulate my new kitten to suckle? My vet says anything under 2 months of age will not be able to nurse so he recommends bottle/dramatization but this lasts only 15 minutes or less before hunger strikes again! Any help would be greatly appreciated!!

Thanks in advance!!
