I'm pretty sure you're right Jayne. Saram, could it be hiccups?

Their lungs don't inflate until their out - that's why they give an almight cry when they're born. I think it's much like a butterfly's wings. The lungs are all sort of squashed up and uninflated and then once they get oxygen in to them they inflate. That's why everyone hangs out for the cry - it's a good sign that things are going well and oxygen is entering the body.

Could be like Jayne says and just swallowing liquid. Yum...........
