Acid Reflux all of a sudden?

I have been lucky that DS was never a big "spit-upper" but all of a sudden, well 4 days ago, he has spit up once a day but VERY acidy smelling. Btu still eating great, and no extra fussiness. Is it common for babies to start having acid reflux out of nowhere? We have a doctor's appt. tomorrow, just wanted to ask you ladies first.

My dr told me that it is common for babies to start spitting up more when they become more active.

My DS was always a spitter-upper but always happy. It got MUCH worse a few weeks ago - as he approaced 4 mos. So its not the same thing but it did seem to get painful for him all of a sudden and the dr. told me this does happen. Hope this helps

ETA: It also has not effected his eating at all - he is gaining weight perfectly and always wants to eat like clockwork...however, he does appear uncomfortable at times.

Reflux is very bizarre to me. My DS#2 had no reflux all day Thurday and woke up with it on Friday Morning... The most amazing thing to me. My ped was not all amazed at all :)
