Maybe a silly question but LO has been crawling and pulling up for sometime now which means he's constantly going for things he shouldn't be. My livingroom is as baby proofed as it's going to get without just removing furniture which (in my opinion) is too much. We have a big space and he has lots of toys to play with but even in the space I've set up for him he'd still rather go pull up on the entertainment center and bang his hand on the tv. I've spent weeks trying to teach him "no," I redirect him to toys or whatever, I remove his hand and say no, nothing seems to be working. If I try to deter him from it he pauses, waits a moment, then goes right back to it. The tv is just an example but it's like that with every thing. I feel like I spend my entire day keeping him out of/away from everything. I even feel a bit guilty for not having a space that he can roam 100% freely in and get into whatever. I know he's growing, he's curious, and it's good for him to explore- but when do they begin to understand and respond to "no" or redirection starts to work?
