Bird and fish fell in love, moved to Spain and had a child. Poor child is bundled up until he can't move by mom and taken out to play hacky-sack in the snow in baby Birkenstocks by dad. Neither is strictly true, but the critter has a cold.
His baby instincts are in high gear and he is nursing a ton, hoping the wonderfulness of breast milk will ward off the cold. He has a runny nose, and we respond by blasting the humidifier and playing in the bathroom with the shower running nice and steamy for hours. Poor critter has not seen un-humidified land in days.
