>it was in Twilight’s nature to overcomplicate things
>while there was excitement when she found out she was pregnant
>it gave way to panic
>she wanted to be the best mom
>she wanted to have everything planned out, everything ready before anything could happen
>what kind of lessons should she teach them? what college would they go to?
>admirable, but trying to preemptively counter every single what-if left her a bit manic
>and in that state she made a mistake
>it was a common practice for unicorns to give their foals a light dose of easily absorbable magic to boost their natural reserve
>there was one problem
>she was factoring in unicorns NOT alicorns
>an alicorn’s mana “battery” naturally grows as they do
>moreover, magic from an alicorn to another alicorn wasn’t additive, but multiplicative
>she more or less gave her child the magic equivalent of a growth boost
>in a blink her belly surged as her foal jumped to the size of a teenager
>she couldn’t reverse it without causing potential harm
>what to do?
>her foal seemed content to sit in lazily in the much smaller space
>not aware that their biological eviction date came and went in a flash of a horn
>…maybe she could sign them up for sports?
