lol it's perfectly normal to worry about all that kinda stuff, i put a couple of towels under the sheet in the last few weeks both times, and once i had my show with Paris about 5 days before i had her, then i put a folded one on top of the bottom sheet as well, which was just as well, because i had just got back from the loo, lay down in bed and felt a pop, and when i sat up leaked everywhere, but onto the towel, yay. it gave me something to carry with me till i could get to the bathroom again and put a pad on. however, none of that happened with Ayja. It always pays to remember that usually you'll have some other signs of labours first, contractions, a show, cramping, all that kinda stuff - only around 10% of women get their waters breaking as the very first, (surprise!!!!lolol) sign of labour. chances are, you'll get some clues first to alert you that maybe a few extra towels on the bed might be a good idea.
