Milk coming out of the baby's nose like this is not normal. Here is my take: Something is wrong with the baby's oral anatomy that swallowing sends milk up the nose. The milk residue left in the nose is why baby sounds congested. It could be that baby aspirates with every feeding but it is only noticeable with the side laying position. I would suggest a video flourescent suck swallow (VFSS in case I don't spell that right) study by an SLP or OT experienced with babies. This test is a bottle of barium given while baby is x-rayed and videotaped. You can see where the milk is going, up or down or sideways! (a joke). I would also be very hesitant to use formula as human milk going up the nose is more benign but formula is very caustic and I would assume baby aspirates on the bottle also. Aspiration can be silent. It can be the always sick baby with lots of colds or upper respiratory infections who is bottle fed formula. Everything can be fairly normal until baby is weaned to formula at which time the colds, etc. start up and never get better. My allergic son was always congested sounding until I removed milk/diet, wheat, eggs out of my diet and we found a new home for the cat. But he never had milk coming out of his nose like this. He spit up quite a lot until the dairy was out of my diet.
