Wife decided to not sleep train daughter, now we have a toddler who won't go to sleep on her own and she has no patience for it

Title basically says it all, my wife was adamantly against sleep training our daughter, now we have an almost 3 year old who can't fall asleep without being held.

Now she only wants my wife to put her to bed and my wife has zero patience with her, she will be in there for all of 5 minutes before leaving her to wail and cry. She was made this way based on how my wife made us put her to bed when she was younger and it really sets me off that she just takes no responsibility in the matter.

What way would you approach this? It often gets pawned off on me, and right now my daughter does not want me to put her to bed so it's a battle for me to even get her to let me hold her.
