This might be a silly question, but is it possible that babies' hiccups can be scared away like ours can?

When I woke up this morning, Cookie very obviously had a bad case of the hiccups. As I lay there giggling at them, I suddenly sneezed. Then nothing. S/he suddenly didn't have hiccups any more and I wondered if it was my fault...

So did I scare them away, or was it just time for the hiccups to stop? In any case, it was really cute
