1 week work trip without 2 year old (literally 24 months!)

As title. We just weaned and my trip is in 1 month, lasting a week, or actually 6 days. My husband, 6 year old son, and mother are staying so many familiar faces for her. She's comfy enough to nap and sleep with both my mom and husband, but we all just know she'd cry a lot after not seeing me for more than half a day. Any words of encouragement?
