Give him some medicine I recomend sudifed. It will help him go to the toilet. You could also try some bloasting pills. It something to do with his throat. I recommend you see a doctor. This could be serious.
Claritin DOES NOT contain Sudafed (Pseudoephedrine) but Claritin D does CONTAIN Sudafed. Clairitin can be purchased easly over the counter but Claritin D has restrictions and must be purchased from your pharmacist. Visit http://www.SCPharmacist.net for health care savings options
I just spoke with my doctor and they said it is fine to take DayQuil while pregnant and breastfeeding. Pretty much if you could take it while pregnant, you can take while breastfeeding is what she said..
