The Woman who says "NO"

Lately I feel like the only word that comes out of my mouth is, "NO!" Gabriel grabs for the dog's water dish, "NO!" He grabs for the ornaments on the tree, "NO!" Zig zags to the back of the tree to hit it, "NO!" Drops food to the dogs, "NO!" Tests me and just puts his hand over the edge of the high chair sans food, "NO!" NO, NO, NO! haha! I feel like such a life stopper. Like my son can't even live life and touch things! AHH! I know I'm training him, but it is SO hard. I want to let him experience everything, but at the same time I want him to respect me and my things. I'm not the type of person to pick up everything he can hurt so he doesn't get in trouble. I would rather him learn his boundaries. What he can and can't do. What he can and can't touch. He is so precious too! He is such a good boy! I tell him no and he walks away. Sometimes he will shake his hand and stomp his feet, but he will walk away. Sometimes he will also test me to learn more about his boundaries. He will put food over the edge of the high chair for the dogs. I will say "no" and he puts the food in his mouth instead of dropping it on the floor. He'll then put his hand off the high chair with no food in it. I don't know what to do at this point! He IS after all allowed to put his hands out to the sides right?! But is he testing me????? haha! So right now I am not swatting him for putting his hands over the edge with no food, only with food. He watches me though. He'll watch me go into the kitchen to wash dishes. He wants to know if I'll catch him even across the room. It's tough training him but I know it has to be done. I'm just thankful he is such a good boy and listens the majority of the time =). I am truly blessed! Just wanted to share...
