Oi.... child abuse. You do realize that most of us are talking about that brief interim where a child doesn't understand when you patiently explain the consequences of a specific action? Unless you have a very verbally gifted baby, or a very physically delayed baby, they learn to walk, crawl, and reach for things LONG before they understand enough words in the english language to explain it to them....let alone the advanced mental comprehension of cause and effect in an abstract way. They have only concrete experiences to connect. "I do this, it hurts. I'll stop doing it." It's not the same as a child being naughty and receiving physical punishment. We are separating the two, you are missing the subtlety. It's not a matter of, "I'll make them hurt and then they won't dare do it again." It's... at that stage of development, if you want them to know what happens in a dangerous situation, you have three choices. 1.) Hope you are always watching and within reach at every single moment. (Trust me, you're not. No matter how vigilant you are. Unless your baby/toddler is attached to you at all times and never leaves your house.) 2.) Let them experience the REAL consequence...cause... you know... then you didn't smack their hand.... they just got burned instead. Much better. Or 3.) Create an artificial version of the consequence that is not going to injure your LO as the real consequence would, so that they still get the point. A swat on the hand. It stings, you point to the danger they were reaching for or about to engage in, say "Ow!" as you do it, and they have a concrete association. You aren't angry, you aren't punishing them, you're showing them what happens. It doesn't take long before they understand what "Ow!" means. Once they understand "Ow!" then you don't need the swat anymore. You can pull them out of the way of danger and just say, "Ow! No!" and they connect it. Not long after that, they're old enough for you to just explain it in normal terms. So you can see, this isn't some smack-happy method of parenting. But whatever.
But... if you feel it's better to just let them experience a burn, or a shock, or other injury...
We don't whack them in the head, yell at them, or anything that causes them fear. We connect the action with the consequence we want them to understand in order to keep them safe.
Bottom line, your comment was uncalled for. I get so sick of people defending their over the line or immature comments with, "I have the right to my opinion...". Of course you do. And there was nothing wrong at all with your opinion that there is no situation in which smacking a child is appropriate. You went too far when you used the term "smacking around" and when you smugly implied that we 'justify it' to make ourselves feel better.
This was, as all threads on here, meant to be a mature discussion/debate. Not a place to attack.
A controlled swat on the hand is far from child abuse.
