Today's a good day for her to have your granddaughter. Her tummy is all baby. She'll be back to her pre-pregnancy weight right after she has the baby. Lucky girl.
WOW!! What is really amazing about having a child is that after it is over, you (as the mom) don't remember being that HUGE! (Kirk, after this is over, you should never tell her she was that big - she could hurt you!! ). She looks as if the baby will arrive any day. Good luck for your DD, your Grandbaby.....and you!!
In about 6 months she is going to look at that picture and wonder how on earth her tummy could have expanded that much. Best wishes for an easy delivery.
