I wouldn't use one. I think its far more important to baby proof your house and keep your small child in sight, if you do those 2 things you greatly reduce the chance of something serious happening. I would consider padding or guards for big problem areas like a fireplace or sharp coffee table but thats all really. I have 2 kiddos so I have been through the "learning to walk phase" twice now, neither of them really bumped their heads much at all, I have never known anyone who's child bumped their head hard enough to cause a serious concern (honestly your child is more likely to go face into something <img alt="" class="inlineimg" src="/img/vbsmilies/smilies/duck.gif" style="border:0px solid;" title="Duck"><img alt="" class="inlineimg" src="http://www.mothering.com/discussions/images/smilies/smile.gif" style="border:0px solid;" title="smile">That being said, if you and your husband feel like you want this for your child, that is your decision. It certainly wont ruin your child for the rest of their life! GL!
