Fussy baby alert!

So our little guy has been having a tough few days. He has been on acid reflux medicine for almost 2 weeks now and was doing so much better a week or so ago on it. Then starting on Tuesday night he took a turn for the worse and has been a pretty unhappy camper since. Poor little guy - you can tell that his belly is really bothering him the way he sticks his legs out in discomfort - that and that he has been crying *almost* non-stop during his waking hours. We are headed back to the pediatrician today. I hope they have some sort of solution up their sleeve to make him feel better...
