Save the dates for baby shower?

My mom and family friend are throwing me a shower on the last Saturday in June (due August 4th). They're saying we should send invitations soon because summer is a difficult time for people to schedule events (around vacations, etc). I feel like it's too early for invitations though. Would it be weird to send a save the date for my baby shower??
