Is there something I need to be doing here because this is crazy......my 8 month old learned to pull himself up and he's really strong! So now that's all he wants to do! The thing is he doesn't have the balance yet so he falls and I'm afraid he gonna crack his head....like the crib, he falls sideways and I'm afraid if he falls hard in the crib he could get REALLy hurt!!!! What did you do????
