All of it was eaten by "Ahhh~".....

feel an english equivelent to what she's saying could be
"I was fed like a child" or something like that.

pretty normal for people to feed their children like alice was doing with mystia here and being fed like that, i can imagine is a little humiliating for some.

I can't make a good translation, but grammatically:

喂: to feed
[啊-]地: adverb of [Ahhh~]

Very literally: All was Ahhh~dly fed inside......
