I am having a terrible time with my girls fighting at feeding time. As soon as they see me get the food out... they start fighting. Their teeth are bared, lips curled back and they start biting & hurting each other. I have to feed my youngest on the counter and my one year old on the floor. They settle down to eat... but continue growl while they eat their food. It is getting so bad that I cannot even walk by the place I keep their food without a fight breaking out. Has anyone else experienced this problem? Other than feeding time... they get along great. They play well, sleep side by side, lick each other and share toys. Any advice is appreciated.
