I wonder how much calories will I burn if I play like a toddler for several hours a day (lol). I watch my daughter go from one activity to another each day and she seem to have lots of energy for all day of play. I don’t think fat burners will be needed if I can burn calories like her. I always have to stop her every once in a while so she can drink her juice or have a snack. Sometimes she forgets all about her milk when she’s playing and having too much fun.
