Hi there! My DS was born 6wks ago at 35wks. He had BS & jaundice issues which kept us in hospital for a week. His bilirubin levels were always just below the Phototherapy treatment line, but only one square. He had 5 days of phototherapy. Managed to establish BF though he continues to have a Ff every night. He's gaining weight well (13oz one week, then 1oz then 11oz!!) so the HV is not weighing him routinely now. What I'm wondering about is the fact that he's not really responding to us yet: a little awareness this past week... But he's not smiling or cooing at all yet. I know my 3 DDS were all smiling in response well before 6weeks. Is the fact that DS isn't due to his prematurity? Is the. 'Corrected Age' term applicable to this? TYIA
