N.A.
My little one had a couple colds where she had a constant runny nose and drip. However, she didn't throw up. HE probably just has a really sensitive gag reflex. I used those bulb syringes to get most of the mucus out of her nose, to help her breathe and sleep!. and try propping him up on a pillow while sleeping so it doesn't drip down his throat. You can get those bulb syringes (buggy suckers we call them!ha ha) anywhere CVS, Babies r us, asically any pharmacy and I think even the supermarket in the baby section). Hope this helps, it is horrible to se lil ones throw up, there is almost nothing you can do about it! hang in there, hell be ok.
