I went to the dr for my sons 2 month appt and everything is great except for the fact that the dr wants me to incorporate more tummy time. He stated my son should be able to lift himself completely up and hold his head up when placed on his belly. He said most babies at 2 months can do this. My son can turn his head and will slighly lift during tummy time. I feel horrible hearing that the doctor thinks that he is behind because of that when everything that i read about milestones shows my son is on track. My son hates tummy time but i will increase his time just to help him be strong and advance. What are your babies doing at this age?
