The reason Vanitas treates Kafka like a baby probably stemmed from the guilt she carried.
Ever since the day she had abandoned Kafka as a baby, that single moment had left an irreparable mark on Vanitas's heart. She had never been able to forgive herself for it, and after being reunited with him—it was as if all those years of suppressed maternal instinct and remorse exploded at once.
Because she never had the chance to raise him as a child—she began making up for it now, except, instead of treating Kafka like the grown man he was, she started treating him like the baby she never got to hold.
And it never stopped.
If anyone asked Kafka what a typical day with Vanitas was like, he could probably write an entire guidebook titled "How to Survive Being a Grown Man with an Overly Affectionate Mother."
Every morning, for example, before he could even make it to the coffee machine, Vanitas would pounce.
