How do I crate train my puppy

i got my 8 week old toy poodle 3 days ago and my only problem is her sleeping in her crate (or not), especially at night. I will usually feed her her last meal min. 3 hours before bedtime and then she lovess to play around with us before she settles down in her play pen (in our living room) or on the sofa in our laps. The problem is that even if shes very sleep, she will whine and cry in her crate for 10-15 mins even after that im not sure if shes asleep or moving around or just changing positions while sleeping. She will whine more if she sees me so i put her in a room close to mine or the living room (naps are no problem, even though I tried to ens that she doesn’t sleep past 7 pm since our bedtime is 11-12) anyways 2-3 hours after sleeping at night she will whine again to pee and then THE WORST OF ALL is that after peeing she gets REALLY hungry so i give her a little food or else she shrieks and cries non sto, and after eating.. SHE GETS ZOOMIES AT 3-4 AM and the whole episode takes 1-1.5 hours everyni and its honestly sooo exhausting because i gotta wake up at 6:30 every day and ive been getting little to no sleep between putting her to bed and taking her out… PLEAsE HELP
