Baby shower invitations

Maria • I`m happily married, & I am a new mommy to a beautiful baby boy & with my new little girl. My life is now complete 💚💜
So I'm having my baby shower next month. So my husband and I decided to get just 40 invitations and hand them out to family members who lives close by, and call those who live far away from us about the baby shower. I was wondering if that's a good idea or would every family members be upset that they just got a phone call and not a paper invitation. 
Oh and we both have a really big family and it's going to be our first baby so everyone is excited about it ha
