Help! I had my guy sim get his girlfriend pregnant and she had the baby, later I decided to marry them and move in together, but they wont let me move the baby with them! He continues to stay at the girlfriend's original house with the grandmom. I cant even take the baby on outings with either nor both parents it will pop up a message saying a young sim was left behind because not enough sims to carry him.....what does that mean?!...Can my couple get their baby?
