Well, first.... sorry you're having a rough patch. Sleeping stuff is hard!
here is my $0.02.
By 2 1/2 my daughter had completely given up all her naps. none. At all. She did have "quiet time" which meant she had to be in her room with absolutely NO NOISE for 30 minutes, or on her mat (at school) while the other kids napped.
I see a couple breakdowns in your post.......
#1
"If she doesn't fall asleep, I tranfer her to thecrib with a book/or toy and tell her that it's quiet time and mommy will come check on her. She will then scream for 15 minutes and I go back in and rock her to sleep."
Your teeny tiny terrorist has found your weak spot and is holding you hostage. it's beautifully crafted subrofuge actually..... from HER SIDE!!!!1 But when you're the mom being held hostage? Then it's maddening!!!!!!!!
#2
"Hubby on the other hand, says that I "need to be patient" and that he allows her to squirm and lets her sleep on him for 25 minutes".
At 2 years old, you and hubby can't have different rules. That just fuels the fire of your teeny tiny terrorist. The two of you have to lockstep and do the high kick. The same routine. every time. from each of you. without fail.
IF ONE OF YOU PAYS A RANSOM FOR A HOSTAGE THE TERRORIST WINS. You're back at square one. You've failed and have to start negotiations all over again..... only this time you have to go PAST the point where you gave in before and then steele yourself for irrational terrorist behavior because you have now confused her.
For an adult..... it takes 21 days of completely consistent 100% unwavering behavior to build a habit. For a kid.... sometimes more. So........ you have to BREAK her habit. That will take 21 days if, and only if, you can be 100% consistent and on the same page. THEN you start the new behavior - that's another 21 days. Sometimes there is some overlap, and you can break a habit and build a habit at the same time....depending on how much of a pushover you have been. The more you guys have given in..... the more it will take to teach her you won't give in any more.
So - the FIRST thing I would suggest is that you and hubs chat it out. Decide what you are going to do. Decide what is most important. To a TONS of parents.... harmony and easy is the most important. So, you lay down with her. For other parents, they sleep train and they are able to be consistent....regardless of her screaming.
Here is what I can tell you with 100% certainty........ THIS issue is going to set the stage for how you all parent. Potty Training. Homework. Chores. Practicing her piano or clarinet. Dating. Drinking. Friends.
Get this right..... prove to her that mom and dad are on the same page and are consistent. That you are not emotional. That she can't wear you down. That she can't win by making it so difficult for you that you give in....... Do this and you pave the way for the rest to be easy. Well, easier anyway.
it's not easy. At all. I'm only 1/2 joking when I refer to toddlers as teeny tiny terrrorists. Mostly they have the ability to make you feel like your brain is hiroshima and the atomic bomb just exploded in your head.
So, stay calm. Don't panic. figure out your game plan. Set it in motion. DON'T GIVE IN.
I wish you luck.
