Anyone had a rough introduction of baby and dog

On the first couple days she did extremely well. But we were sitting calmly and the baby sneezed which startled her. Now whenever the baby cries she is barking and whining and wanting to be held. I left the door open I have a monitor over her bassinet to switch laundry (everything in apt is on one floor) She was in the living room the baby whinnied and she rushed across the apt. managed to use the furniture to jump in her bassinet. I didn’t give her time to see what she would do. She my college dog from junior year and my baby. I really don’t want to rehome her. What have you done or did with your pets and baby
