Leaving baby with mom

Kara • Married 🇨🇦 SAHM Girl 09/09/16 -x- Boy 08/29/19 Waiting to TTC #3

I am going to leave my 7 month old baby with my mom next weekend. She has stranger anxiety and though we see my mom at least once a week she still cries of she takes her from me.

I know she's going to cry but I owe my husband some us time.

My mom has been around babies her whole life and I know she can handle it but it just breaks my heart.

How can I make it easier on my baby?
