help! DS is my first so I'm clueless about this stage. A few weeks ago he started pulling himself up to stand and climbing on things. He's a very active little boy so he's doing this all day. The problem is hes falling and banging his head. We've got a playpen but I can't keep him in that all day and I've tried to baby proof as much as possible but he just finds something else that I hadn't thought of. And I can't always get to him quickly enough to catch him. Does anyone else have a very active little one? What did you do? When can you start to teach them that some things are not safe (DS is only 8 months and doesn't seem to understand)? Will he ever understand the word No?! Thanks for your help/ideas!!
