It's strange how that happens. I have about a dozen cousins all within a month or two of my age, so my mother and all her aunts must've all gotten pregnant at roughly the same time despite getting married years apart. For some of them they'd already had other kids, but for most it was all the eldest. Weird how it works out.
And 3 of my 6 children all have birthdays within a week each other. Last week was "birthday week" in our family.
April 2, April 4, April 5.
Would have been cool if they had all been born the exact same day. I've seen some articles which appear to prove that the first Easter Sunday was on April 5. So that would put my kids' birthdays on Holy Thursday, Holy Saturday, and Easter Sunday.
Of course the children don't want a joint birthday, understandably, because each one wants their own special day.
