Separation anxiety

Hi guys 👋🏼

My baby is 6.5 months old. She’s already started having some separation anxiety especially at night. Her father will be meeting her for the first time when she’s 7.5 months old. I’m so scared that she will be scared of him or won’t want to be around him. He will only be here 2 weeks before he has to go back to work. Anyone experience this separation anxiety and have any advice or tips etc ?
