I'm sure you have by now made your decision but I just wanted to tell you as a mother of two I have plenty of experience here. I have a daughter Presley who is 4 yrs old and my son Nixon is 18 months old. My children are two different extremes when it comes to getting and being sick my daughter is blind(she was born that way) and she is often sick she is a normal healthy child but the reason why she is blind also affects the part of her brain that affects the pituitary and she must have growth hormone shots daily which in turns causes her to easily get sick, she has just always been the sickly child. My son though has really on been sick once and even then it wasn't that bad. He has never even really thrown up!
So my advise seeing as how I have had to adapt to both extremes is always call your pediatricians on call and see what the Nurse thinks. That is why they are there and trust me they don't mind you calling. I would NEVER take the chance of wasting $100 on a needless doctors visit. Give your child a chance to fight it off besides you don't want them to be out on antibiotics to often or they will get immune to them
I hope everything worked out and your sweet angel gets well soon. I have found sniffles and coughs are pretty typical and usually you get told to give them Tylenol or Motrin as needed, plenty of fluids and lots of TLC!
