If possible, have her around some other babies soon so she knows they cry and smell funny. When your new baby comes have husband hold baby and you tell her how good she is. Let her smell baby things. Don't yell if she comes to see new baby. I let Trixie smell baby's foot. I had to nurse my baby on the couch so Trixie could sit beside us. As long as they know they are still important, most dogs do fine.
