All children love to walk through puddles! Like to slap on the water to the spray was flying around. Parents usually forbid it to do, take the kids away, attach "hot spots". Try to understand the desire of your child, give him the opportunity to accomplish it because nothing bad in it!
After the rain, going for a walk, put the kid boots, clothing that does not get wet and easy to wash. Should also dress appropriately. And walk yourself through the puddles. The baby will be happy. Don puddles were not too deep and the water did not get into the boots, and try not to splash the nearby people.
