Gender disapointment

Kris🐶🐶👶🏼
Just had our anatomy scan today and its a girl 😁😁 and its not me thats dissapointed, its my husband. Hes actually mad. Like i had any control over it at all. Im not really sure what to do here. Maybe after i give birth i can just trade her in at the hospital... (Not being serious)
How do you help your husband cope?
