Hello. My 4.5month old baby boy, born premature at 33 week 5 days (corrected age is 3months) needs to be forced to makes eye contact and when he looks at us he keeps staring. He only rarely smiles at fathers face and in mirror while seeing self. Also, I have noticed he is not that playful and does not get excited when he sees us. Is it normal for premature babies to have such development delays. Doctor has suggested to wait until his corrected age is 4months but I am concerned if this is normal.
