When is a good age to start teaching discipline, like NO don't play with that ETC.?

Dicipline is a strong word. But yes I would think it is helpfull to teach him boundaries from an early age like things he can't touch. however he may not fully understand untill 12 or 18 months old. He may at first only become aware That some things He does produce a reaction from you ,such as He touches something and you say no, but he will not fully understand what you mean .he will repeat the touching of the object to explore the relationship between his action and your reaction to it to try and understand it . babies often learn through repetion. He may also enjoy learning that he produces reactions from you and that his actions affect others. As he gets older like 16 to 18 months or maybe a little earlier since his language sounds advanced he will understand that you are setting boundaries and will then test them . Simply be consistant and at 2 or 3 years it is important to explain the reasons behind boundaries such as safety so he knows it is not a battle of wills or a game but because you are looking out for him . Sorry if that answer was long. Basically it is not too early keep doing what you are doing but realise it is a gradual learning process that builds over time. Distracting him is a great strategy to move him on to a new activity. You can move him or give him a toy or just tickle laugh or sing also try moving things you don't want him to touch out of sight or out of reach especially once he can crawl.

From everything I've read children understand at a very early age; particularly the word no. However, at 7 1/2 months he isn't going to stop doing something just because you say so because he doesn't understand the consequences if he doesn't. I don't know what you can do about computer cords but I've seen examples in advertisements about ways the cords can be lifted off the floor; you really should look into it. Child proofing is very important to protect him. Also who wants to be saying no all the time when he is just exploring and doing what little people do. Why don't you buy a very good book on child care which walks you through all of the stages and gives you practical advice?

Now is a fine time to start, he may not totally understand you right away, but there isn't a reason why you shouldn't begin mild discipline at this age. I have been telling my daughter "no" and redirecting her from what ever it is since she was about that age - Now at 1 years old she seems to understand what I am saying (but doesn't always respond), its all about learning and introducing boundaries, so long as you don't expect immediate results and your actions are mild (use a stern voice rather than shouting/no hitting etc) then carry on with what you are doing.

I think your instincts will tell you, as they are already.

It is too early for you to get upset with him for not listening to you about it, but it isn't too early to have some rules.

For my guys it is no standing in the bathtub, and don't touch the dishwasher. I say "no" and help them sit down when they do it. Everything else I just child proof.

If he is "getting into everything" I would highly recommend child proofing so that there is nothing he isn't allowed to get into. I have superyard XT gates around the computer and TV. You can get them from Amazon.com for $50 and they really do work well.

No matter how much you child proof etc. you will still have plenty of opportunities to teach him no. But you want to try to say it as little as possible, so try to make your place more baby friendly, so that getting into everything is okay.

He is testing you. It sounds like he understands. Keep removing him away from what he can't have and distracting him with something he can have. Try not to use the word no too frequently, instead say that's dangerous to touch come and play with this instead. Give him a reason why he can't have something. Congratulate him when he does as you suggest. Babies will continually test parents as they explore the world but persevere and don't give up. Babies and children and obviously curious . He wants something cause he can't have it so just explain.

Start him on no now. We started telling DD no around 6 months. We don't tell her every time. We usually say no then if she continues we remove her from the situation. She's now a year old and she knows what no means. She will go up to something and we will say no and she will look at us and move along to something else. Every once in a while she does her evil grin and does it any way but kids will be kids lol.

This is the right time to start, but he is already testing boundaries to see how much he can really get away with. Keep doing what you are doing and he will understand soon!

you should start teaching discipline as soon as he says his first word
