My DS 3 1/2 has had a really nasty virus and cough since Saturday and is eating very little, I went with the flow at first but he really isn't eating still. He's having plenty of fluids and sleep but just doesn't want food. Yesterday he ate a couple of spoons of cereal, a couple of spoons of pasta and a chocolate biscuit and today a couple of spoons of cereal and a fruit puree and it's been much the same since Saturday? Should i be calling the dr again?
