A very essential part of our daily schedule is being in green surroundings. My mini is one wild child and can not call it day without being at the parks at least once per day.
Why it is essential to take kids to the natural surroundings more than indoor play areas?
Primarily, because there is so much to learn and gain from nature. Kids improve and build their fine motor skills, observations, creativity, imaginative thinking, problem solving so much better when they are left to play in natural surroundings. No books/ educational toys can ever teach a child what a hands-on experience with nature can.
Although we are not morning people at all, we have switched to visit the gardens early morning instead of/including the evenings because we feel that the early morning sun and fresh air do so much to improvise us.
