My DS is 5.5 months old, he's not sitting up on his own yet but is rolling and starting to push up and rock on his hands and knees, which makes me think crawling might not be far away. I'm wondering if I should think about lowering his cot base to the lower setting now before he reaches that stage? I can't remember when I lowered DD's...I know it was no where near this darn early though!
