Hard to say really Jayne. I know with Lindsay, DH had a look (and I have no idea why LOL) and he said that I bet you that the baby will be here in a day or two and he was right - he was born two days later. With Erin it came on about the same, but with Paige it was hard to tell cause it was already puffy, but got more so when labour started. I don't think you will have to tell him, he has probably seen it hundreds of times.
