Now that LO is started to pull up, I'm worried that she might fall and bonk her head on the floor. We have tile and hardwood floors. Should I pad the areas for her? What do you all pad your floor with? I think there's some carpet padding I can put under rugs, right? I have one area where I put those soft foam tiles under a rug and that seems to be okay... but my whole first floor is noncarpetted, I can't pad the whole thing! What did you all do?
