Did Snow White have a short pregnancy または did it take Regina ages to cast the Dark Curse?.

Good question. Well we will find out this season.

によって the way, writters didn't pay much atention on details. I am still wondering with Snow White's sentance in 1st episode "She poisoned me with an 林檎, アップル just because she thought i was prettier than her"

Good question. The writers apparently don't care about details (coughcoughtheyneedtocoughcough). So yes, Snow could have had a short pregnancy and yes, Regina could have taken a ridiculously long time to enact the curse, but have あなた consider this... It's the 魔法にかけられて Forest. It is magic! Maybe the standard pregnancy time is however long it took Regina to enact the stupid curse. So yes, technically it would be short pregnancy to us, but it probably wasn't to them. But that's just a theory... a film theory (F.Y.I.: That was a reference to MatPat's Film Theory... it's really funny)!

I think it just took Regina a long time to get the Curse back from Maleficent and possibly also to gather the ingredients and equipment necessary. We know that she had one failed attempt too, when she thought that her horse's ハート, 心 would be enough of a sacrifice.

I also think that Emma was a little bit premature. Snow and Charming had planned for a still pregnant Snow to go through the wardrobe portal, so they expected her to still be pregnant when the Curse came. Emma couldn't have been very premature though, since she survived as a baby without any sort of healing.
