Wow this is a TERRIBLE advertisement... I agree with so many other baby-wearing moms out there -- WHAT was Motrin thinking?! If nothing else, it is completely ignorant in information.
Wearing your baby correctly is SO comfortable - for both Mom and Baby -- it leads to a MUCH happier baby and mom! There is no pain involved. If anything, it reduces the "pains" of early babyhood. Juneau is pushing 19 pounds and has been worn since birth. He is going on 4 months of age and has never once been in a stroller or left in a carseat. This absolutely leads to his feelings of comfort, security, safety and happiness - not to mention a more secure attachment and bonding between the 2 of us.
