So loving and kind. I would like Fluttershy as a sister.

She has a knack for taking care of living things and she's very kind. She'd make a great mom.

She's my favorite, next to Spike...

I would never be bored!

I would love having Fluttershy as a mother. She's so kind and caring...

I bet AJ would make an awesome mom....fun, free-spirited, fairly wise, tough but helpful and caring...I bet Cadence and Celestia would be particularly great mother-material, too. Perhaps Luna as well, now that she's beginning to readjust to to "normal" life in Equestria among other ponies. ;p

I like picturing Derpy as Ditzy's mom, and doing a good job as a single working mom. I think all of them would be amazingly great in their own ways, but also need to work on things (e.g., Twilight making more time for the kid, Fluttershy having to toughen up a little sometimes [though she has had some valuable experience dealing with three rather difficult fillies at once, and has The Stare as well as extreme tenderness and ample love on her side...d'aww], Dash and Rarity having to learn to take it easier on them and, like Twilight, perhaps learn to practice patience a bit better...)
Pinkie has begun to learn such lessons via her foal-sitting adventures, so while she still seems a bit on the immature side, I think she could pull through for young ones who needed her. Celestia knows she too would be one wacky, crazy, super-fun mom, being so childlike herself...maybe a little too nutty for some kids at times, but...xD

Either her or Fluttershy. I just feel like Rarity would be a good mother. She's generous and even though she's over dramatic, she knows how to handle little fillies and put her hoof down every now and then, so I'd be well disciplined.

Of the mane six I think Pinkie Pie because she's already had her practice with The Cakes Twins. Cadance I think would also make a great mother because she used to foalsit Twilight.

She would make me the beautifulest girl in school and learn me about fashion and charisma. Rarity is generous too and knows how to handle childs, so what Shadirby said. And she is an amazing fashion designer too, so you have lots of money if someone buys it. She would be the perfect mother!! :D

^This

i love rainbow dash and she is tomboy and i want to be like her she is awesome she can fly miles high

FlutterShy because she is so sweet.

Twilight she will be a great organized mother and will always help me if I had problems

princess luna. she is princess of the night my favorite time of day. she is mature and can be pictured as a mother. plus since she is awake mostly at night she is the perfect mother since i have insomnia. princess luna would be the perfect mother for me :)

P.Cadence she is pretty and care

I chose Cadence 'cause I wanna have a daddy ^-^

Princess Cadence, Princess Luna, Fluttershy

Aw, Fluttershy would a be a great mother.

I picked chrysalis -_-
Even though she is evil i found her better as a stepmother i would learn how to dress up as people and lock them in caves MUWAHAHHAHAHAHA LOLZ and if i had fluffle puff i would hug her so tightly :)
