Well, it could be a million different things. My 5 year old started to show symptoms of IBS around age 3. He would get tummy aches after certain foods and it could last a day or two until he felt better. He went through a few weeks where he felt like he was going to v* daily. It wasn't a bug, he just didn't feel well. Toddlers often have stomach aches, fortunately it's rarely a bug. Being that he's so young I can't imagine that he has a sv* and isn't exhibiting v* or d*. That's my honest opinion!
