O My

He's too young to know what you're saying. Distraction is the key. If he has something he shouldn't have, give him something he can have. If he's starting to go somewhere he shouldn't, get his attention so he will go somewhere he can (or pick him up and put him there).

It's going to be ahwile before he can understand what "no" means.

Redirect him. Completely normal for O..

.

Babyproof the heck out of everything in your house. If he grabs hold of something he shouldn't have, say, "Thank you!" and take it from him, as if he was just handing it to you. Or just give him something to play with that he CAN have. Basically at this age, pretty much until he is 3 years old or so, you need to set up your house so you don't have to tell him no all the time. Make it a safe place for him to explore (put up baby gates in areas he can't play in). The less you have to say NO, the more he will listen when you do. Save NO for the times when he is doing something dangerous, and try not to say it much at any other time.

At this point he is just trying out a new word and seeing what a fun reaction it causes.

He is mimicking you and making a game of it, and slowly understanding what no means. Keep redirecting his attention.

Dr. Sears has some excellent advice on this.

Your little guy doesn't think yet in terms of "what's right" and "what's wrong," he crawls away because he's learned YOU are about to take something away. He's just beginning to learn that there is power in telling mommy no, "playing" the same game that you are, though he hasn't figured out yet exactly what it means.

It's much more effective parenting to learn how to give your son as many "yes" messages as possible, before he starts just tuning you out for your repeated "no's." This would mean keeping all things that are not appropriate or allowable out of his reach, and preferably out of his sight so he won't get whiny trying to get to them. If you have to take the same things away from him over and over, you have a problem you can correct. It means having a toy that he likes, or maybe some pans and a wooden spoon, or a "dead" cell phone or remote control (you know, all that cool grown-up stuff) handy for him to play with when you do occasionally have to take something away from him. Or an attractive, healthy snack if he clamors for some food he shouldn't eat.

Do check out Dr. Sears' website, as Momma L suggests. There are lots of good tips:

That is totally normal behavior for a one year old! My son is also one and at his 12 month checkup after he got his shots he stoped crying, smiled at the nurse, and said "No-no!" Your son is still just a baby and even when you think he "knows" that he is doing somehting naughty, that doesn't mean that he has developed the self control nessesary to chose NOT to do the naughty thing. Also, most of the time he will just practice talking by saying "no-no-no," just like he did with "da-da" and "ma-ma." He usually doesn't MEAN anything by it, he just wants to talk! Baby proof your house and don't leave thjings that he should not get into down at his level, then let him play and explore in a safe environment. Don't be one of those people who is canstantly telling their baby no or even slapping their little hands, that kind of thing just breaks my heart.

I would save no for times that are serious like when something is dangerous and when you say it mean it. Take him away from the item or take it away from him and be consistent. However, you also need to help him know what he can do so give him another toy and as he gets older say things like "use a quiet voice" when yelling or "keep you feet on the floor" when climbing. We also use sign language for our one year old to help him communicate. When he is all done eating we have taught him the sign "all done" so that he doesn't slap the food away and make a big mess. We are also teaching him milk, food, more, blanket, and bath. This next year to two years will be a lot of him testing you and you keeping him out of trouble. If you are consistent it will get better as they grow.

Change it up he is telling you 'mommy i am bored of the no no' and make sure you are FIRM and do not have a smile or frown on your face when you say it.

Both of my kids went through that, my son a bit more than my daughter. There are times when you really do have to say no. Like when he's reaching for the burners on the stove, or something, but then along with saying no, you have to get them immediately away from that object and re-direct. If he goes back to what he was doing, you say it again...we also gave a reason like..."Hot! BIG OW!!" because he can understand that at that age. If it's not such a huge thing, a simple "That's mommy's!" or like someone else said "Thank you!" and taking it away. The risk you run with the "thank you" is him thinking he's doing something right and him repeating the behavior, probably with everything in the house he can reach because, well, you did thank him! So a "That's mommy's" or "Let's go play with your truck!" might be better. And then give him the truck. My daughter was famous for going back time after time to the electrical outlets (that was a "no" moment) and no matter how many times you re-directed her, she wouldn't forget what she was doing and she'd go back. We had safeties on them, but still, they do have to be told no SOMETIMES or they won't know what it means. When my daughter would go for the outlets multiple times, I would slap her hand lightly to get her attention. It might sting for a second, but I would rather that than electrocution, so when it's a matter of danger, you HAVE to do something to get their attention. I think I only had to slap her hand twice and I don't think I hit her hard enough to hurt her because she didn't cry or anything, just looked at her hand and looked at me like "What did you do that for?" You have to decide what you are comfortable with, but this is very normal behavior for a 1 year old.
