Because you are so far along, I would just call your OB!
I would go to the dr and get checked better to be safe that's what they are there for xxx
I would definitely call your OB, this can be a sign that the baby is under stress. they will most likely have her go in and check the baby's heart rate and stuff to make sure all is ok. They do tend to move less as they get big but better to be on the safe side!
Being that she is 39wks along movement can sometimes stop because the baby is already in the birth canal and moving down into position and she could be closer to giving birth than she thinks. I dont believe there is anything to worry about, this always happens before the baby comes. The birth canal is much smaller than the stomach so not much room for the baby to move around in. But, she could call the OB just in case. God Bless your family, and congratulations!
Thank you - I am the one who is stressed, this is my first grandchild..... I am relieved and thankful for all your answers. She is at the doctor's office now and they will call me with details. It's been such a long time since going through that that I didn't have an answer for her, just mentioned that she should call her doctor. Good to know that was on the right track. Again, thank you for the support!!!!!
