Booster Girl, The Lord works in mysterious ways and if He says it was not time for the four little eyes to see the lightness, then I am afraid it is just his will.
However, he has deemed that your daughter and the father are capable of procreation, and thus in time they will deliver beautiful children, just like their Grandmother.
Who knows, it may even be triplets next time???
Then you really must get those fingers working. Knit one, pearl one, knit two pearl one.
