Take your baby to beach or sand pit and see how satisfied he is filling and emptying the sand buckets. You may feel that this is such a boring game but your baby is actually practicing all his motor skills and hand eye coordination. At this age he would find emptying easier than filling it up. All the filling, lifting and carrying is also helping grow his muscles.
What you need to know
Children this age love to do the same activity again and again. It gives them great satisfaction to know that they know the outcome and sequence of the activity. Sand pits are actually great place for fun, learning and development for your child.
