Toddler & newborn!!

I have a two year old who has been rough with/around our newborn who is less than a week old. We’re working on being gentle and easy with/around baby! But it’s giving me so much anxiety, I’m afraid one of these times baby will end up getting hurt! He seems so tiny and fragile, doing my very best to be on my toes with them both! Anyone else deal with this?! Please tell me I’m not alone!
