I like very specific themes, so I have read several fics in this style, but I would like to know if there are any recommendations of fics with the themes below:

1 - Time travel where Kagome meets Sesshoumaru as a child. Or even a story where both are known as children, but Kagome years later still falls into the pit and is still the miko of the jewel of four souls.

2 - Fic where Kagome takes care of the son of Sesshoumaru as a surrogate mother, who is compatible with the canon in some way and not an AU fiction.

3 - A fic where Kagome and Sesshoumaru create a son, not a baby, but a child who may or may not be their son in the feudal era.

4 - Strong Kagome, or a fic where Kagome becomes stronger and a better fighter.
