When in doubt always consult a physician.
Babies are extremely sensitive to smell.
Babies can recognize their mothers' scent and distinguish it from someone else's, as early as six weeks old. This may be the first connection for a loving bond between mother and child. We experience life at this young age largely through our sense of smell. Fragrance pleasant or not, comforting or not becomes a memory. As a child, I would love our family trips to the beach.
