Possessive 22 month old

Marzi

I'm having my c-section Wednesday and I am really nervous about how my 22 month old will react to the baby. She is SUPER possessive of me. She doesn't even let my husband, her father, get close to me. The only person she really allows in my space is her big sister that is 9 years old. I don't want her to hurt her new sibling. HELP😪
