Love Tap has a reputation for being excellent at taking care of children. Twilight needs somepony to help look after the sirens. These two things really shouldn't have any connection, but desperate times call for desperate measures.
Spiritual sequel to The SweetieMash Chronicles. Though reading SweetieMash is not compulsory for enjoyment of this story, it helps fill some blanks.
