The first thing I do in the morning is to feed them. As soon as the family has eaten their 1st time, I check each one on the detail screen to see how the "hunger" and "energy" levels are. I feed twice if need be, sometimes the kids need a third helping. Then, several time during the day, the more productive the parents are, the more naps they seem to need. *** If I encourge excercise, the energy bar does increase. Staying in shape has its benefits...
At first, I used to use the red hand whenever they checked their weight...(had visions of vain anorexics....) but that was a mistake. Keeping tabs on their weight leads them to stretching on their own, then quick work outs and so on...
