Spring has officially arrived, and
here in the Midwest, everyone is out enjoying these first days of sunshine. My
toddler points at the door all morning, begging to go play outside. Now that
she's experienced the grass between her chubby little toes, she can't get
We were chatting across the fence with a neighbor when I noticed our
little one had wandered over to our garden, which of course right now is
nothing more than a dirt patch. She was
squishing the black soil between her fingers, watching it fall back to the
ground. She ran across a big hunk of dirt and, because it's what toddlers do,
she promptly started chewing on it. Even though I know the facts about babies

According to the hygiene hypothesis, our
obsession with cleanliness, especially around babies, could be to blame for the
surge in all manner of allergies in recent years. The idea is that, in the
absence of new bacteria and germs to fight, our bodies' immune systems

important during early pregnancy and the childhood years for growth."
Another study showed that babies under age
one who were exposed to far nastier stuff than just dirt (rodent and pet dander, roach
allergens and other bacteria) had a lower risk of developing asthma and
So by all means, let your baby play in, and
yes, even eat dirt. However, use common sense: If you treat your grass or
garden with pesticides or other chemicals, you certainly don't want your little
one ingesting that.
