I don&#x27;t agree. A 10 to 14-months old baby weights 8-10kg on average, and often can&#x27;t stand reliably. For many people, carrying that kind of weight for any significant time can cause health issues, especially if they&#x27;re older and&#x2F;or the ride is long.<p>As a son of a women with scoliosis (a chronic problem which affects 2-3% of the US population), I with people weren&#x27;t so prone to assume laziness or selfishness.
