Can someone pls tell me more about tummy time. I pop my DS (10 weeks) on his tum, and he looks pretty bemused, pushes around a bit and sometimes lifts his head, but doesn't seemd that enthused. I lie beside him and chat away and he can lie there happily for a while, but I am not sure what should be happening. How often should we do this, should I be doing more when he is there etc?
