I'm not gonna make it. daily the gilrs scream & fight ALL day long over toys, food, sippy cups, etc... They will hit & bite each other for possesion. My nerves are fried! Is this a twin thing? They're only 16 months. how many more years? HELP! I hate that I cant wait for thier bedtime many days. I think it is time for a nanny and for me to move...
