Did
you know that the "new baby smell" is thought to be nature's way of
protecting the newborn? It lasts about 18 months, and causes
humans, and animals alike to be protective. It also compels us to
hold new babies, which tender contact probably has something to do with
a normal development. Joe Stalin, for instance, lacked this
pheromone, smelling more like cat urine. A resultant lack of
affection turned him to a path of megalomaniac socialism. Or,
that's how I heard it.
Here' something else.

Children
run less risk of being sensitive to allergens if there is a dog in the
house in the early years of their lives, scientists have found.
The conclusion, based on a six-year study of 9,000 children, adds
weight to the theory that growing up with a pet trains the immune
system to be less sensitive to potential triggers for allergies such as
asthma, eczema and hay fever.
The “hygiene theory” of allergy holds that modern life has simply
become too clean, meaning that babies’ immune systems are not exposed
to enough germs to develop normally.
Having a dog provides enough dirt of the right kind, the new German
study suggests. But it may be important that baby meets dog early
enough to affect the immune system as it develops. “Our results show
clearly that the presence of a dog in the home during subjects’ infancy
is associated with a significantly low level of sensitisation to
pollens and inhaled allergens,” said Joachim Heinrich of the National
Research Centre for Environmental Health in Munich.
The same protective effect was not seen in children who had frequent contact with dogs but none at home.
