"I bet you're hungry. But we can fix that in no time, my little darling", April said in a cooing tone. She put the baby down on her bed.
Garret, while still crying, noticed his/her sister's breasts seemed to have become significantly larger, especially now as she unbuttoned her blouse. He wondered why she did so, but then it became obvious: She was wearing a nursing bra with detachable cups. As she exposed her left breast, Garret cryed even louder and wriggled about in shock, her little arms and legs thrashing about in the air.
"Sheesh, you must be starving. But now it's lunch time!" April picked the infant up despite her protest and sat down comfortably. Garret's eyes were all blurry from crying, but she could still see the big dark nipple in fromt of her as she was pulled towards a boob at least as big as her head.
She wailed even louder than before. "Come on, yummy yummy" April coaxed, but the baby refused to latch on by herself. Garret heard her sister/mother saying "I think you need a bit help" as she was pulled even closer and felt the nipple and areola fill her widely opened mouth. Instinctively, she stopped crying and started to hastily gulp down the warm, delicious mother's milk.
"You see, sometimes if you don't want something crying isn't the best idea, my little pumpkin. But you still have a lot of time to learn such things..." Garret barely listened as she concentrated on suckling, forgetting all of her anger and discomfort. Being a baby girl was really nice, for the moment at least.
