What works with babies/ toddlers

Ok, My questions is how to disapline a 10 1/2 months old child I have tried telling him No, I have tried slapping his hands when he gets in to something but he just laughs at me, my biggest problems is with the phone I've tried moving it he just still finds a way to get to it, I will sit there and tell him No and slap his and and he just grabs for it agin I've done this repeataly for about five min. before I give up. Is there anyone one our there with any advice are new ideas

Do not give up, if you stop now then it's only going to get worse. He obviously is not taking you seriously when you slap his hand. Now you need to use harsher methods to get your word across. Try using something he likes or activities he likes to use as punishment. For example if he likes to watch a show at a certain time, then when he's disobeying you tell him firmly that he's not going to watch it. It's important to tell him at the time of the action what his discipline is and later to reinforce it. Small children will sometimes forget and need to be reminded of why they can't do what they like. Also it's important to never go back on your word. If your child sees for one minute that you are willing to soften up then they will see that they can walk all over you making even worse to get them to listen. Just keep firm with what punishment you set and make sure you get across to them that if they listen then they can get the things they like. If your husband or the father is active in disciplining as well make sure you two are on the same page. Good luck.

my daughter has a 12 month old that she loves dearly . the baby is a little spoiled HA-HA why won,t the baby stop when she is being changed . does it have something to do with visits to the doctors for shots ?Is the baby afraid that every time she lays still something will hurt her?why? is this behavior going on?
