How to deal with baby 10m who insist to climb the coach when i say no firmly he still repeat the same action how to change his behavoir?how raise obey

When you say : in a low, firm, calm voice, remove him from the couch from behind. Take him to a play area & engage him in a different activity. Spend an afternoon redirecting him till he " gets it." Negative or positive attention reinforces a behavior. Raising your voice, scolding or appearing upset will reinforce his couch-climbing. Ignoring a behavior by using time-out works from 18 mos. to 10 years.
