Ooh, I can't decide whether to change my guess to 15th April. All different months, but DS1, DS2 and my birthdays are on the 5th, 10th and 20th, so adding the 15th to the pattern would be pretty cool. I'd be 38+1 on 15th April and it's a day when the boys are in nursery, so a good day to disappear off to give birth, but I'm just not sure it'd happen that early when my other two arrived at 41+1 and 40 weeks. All round I think it'd be a good date though, so I think I'll make that my guess.
