Last time we did it via online. But you need to capture baby when he is awake. We put A4 paper behind his head as background. Then cropped the size then upload. I forgot the processing time already. But I do remember you need to bring your newborn at ICA in person to collect the passport. Do call ICA to expedite your case. Tell them your reason and I believe they would help.
