She seems like a nice, caring mother, but we don't see much of her, so...

Queen Grimmhilde
Lady Tremaine
Mother Gothel
Ariel
Naveens Mom
Queen Elinor
Fa Li
Grandmother Fa
Queen Athena
Mrs. Potts

Now it is getting hard...Queen Leah made a great sacrifice by giving up her baby to save her, but I don't feel we really got to know their mother-Daughter relationship and personally if I had been separated from my child her whole life I would be attached to her constantly and would not be able to stop hugging and cuddling her...

she didnt care that flynn had stolen from her, something very close to her heart in fact, she just accepted him and the fact that her daughter was marrying a thief. dont get me wrong i love flynn, but that wasnt good on her part. and why did they never find the tower? did they give up before they could search that far?
also like with leah we dont see much of her, in fact she has no speaking lines at all.

i dont think any of the three are actually bad tho =)

Not much to know about her.

Okay personal I think she could have kept Aurora, Maleficent said on her 16th and she had a long way to go until 16. But I guess she was playing it save. After this it's going to be hard

I think that she is the worst because she totally let her baby slip away from her. And then she let Flynn steal the one thing that she had left of her baby, and she didn't even go looking? Um yea I think Leah is a way better mom, than rapunzel's.

Not Leah, she made a great sacrifice giving her baby daughter up! Rapunzel's mother didn't have to do such a gesture. she's not bad, but she's rather passive, she doesn't do much.

It's a hard decision, because Leah made the hardest decision of all of them, giving up her child out of love. But considering that there were also plans to marry Aurora off more or less immediately after she was back - well, Leah wasn't the mastermind behind it, but nevertheless, a little bit more consideration for Aurora's feeling all around would have been nice.

She doesn't have a lot of interaction with her daughter, so it's hard to decide how good of a mother she is.

Either her or Rapunzel's mother.

She's not bad but I think she (and the father) should have searched harder to find their daughter

Leah did the hardest thing she could in giving up Aurora in order to protect her! She put Aurora above all else!
We just don't get to see as much with her and Rapunzel as we do with the others, we know she was sad she was missing (but seriously, if they walked in on Gothel leaving, couldn't some horsemen have beaten her to the city gate? I digress,) which any mother would be, and that they sent up the lantern tribute in hope she would come home every year, and she hugged Rapunzel once. Other than that, we really don't get much of a view of her with her daughter.

She doesn't really show much care for Rapunzel IMO

All three of them are great mothers, I don't participate in these countdowns because Its hard for me to decide.
