Keep her/him indoors and at that age give him/her anything and everything he/she wants. At that age, there is no point in trying for "healthy." Being alive is "healthy" so just indulge your baby.
We really do. She had cancer this past year and we had her operated on. She got so thin and weak I thought it was the end. So we spoiled her totally. Then she got better. Now she still expects 2am feedings, tuna mixed with her food, treats from the table and to be allowed to sit on the stereo. And of course, we indulge her.
