I tried them all, pineapple, spicy food, long walk using the gutter, blowing up balloons??? and then blowing up balloons whilst squatting (nearly peed myself then so stopped that) even went to my last resort.....sex. But Matthew came 7 days overdue missing both my parents who went back to brisbane 12 hours before he was born. So I believe that it is purely coincidental. But good luck anyways!!!!
