I've found myself comparing my did twin boys vision. They are three months tomorrow and Asher looks at me in the eyes and responds and smiles. While Leon doesn't connect with his eyes with anything. He smiles and coos at me when I play with him but I almost feel like he avoids contact with me. It has me so stressed and freaked out! I'm hoping he will soon. I feel like I wouldn't be worrying if I didn't have two to compare.
Re: Divelopementally comparing has me freaked out.
But as pp said, there's a wide range of normal. And I agree, that they switch being the first to achieve milestones.
ETA sorry, I was not really thinking in terms of the age for eye contact...I would just call the pedi & ask at what point to worry or set up some vision testing for peace of mind, maybe they can get that done easily to help ease your worries...
