My two month old not recognizing me.

Hi doctor, my due date was march 11 but due to less baby movements my doctor induced pains and my baby was born with normal delivery on March 3rd with 2.5 kg weight after birth she is not good at feeding and had a severe jaundice and was admitted for phototherapy discharged with weight 2.26 from then she is having gastric problems and not having proper feeding she is now 2 month 10days old and weighing 4.1 kgs. She is not recognizing my face or if we try to move any colored toy in front of her she is not moving her eyes but she looks forward sides and backwards also when we try to make eye contact with her she doesn't see us she looks into sides or upwards.. She laughs herself but when we try to make her laugh she doesn't laugh.. But she is responding to sudden sounds, keeping her hands into her mouth, moving legs and hands sometimes she tries to head up in tummy time(not always) Is this a problem why my baby is not recognizing
