It sounds like your baby loves to run on the treadmill! Can he get off if he wants to? Does he pant excessively or tire? If not, sounds like he is fine on there! I wish I could do it. If you are asking if he "needs" the exercise every day, the medical answer is "not really" but if he loves it and you can give it to him, then he is a very lucky boy. Good for both of you! I would love it if you would send us a fun picture to post!
