I am so ecxited about my son getting n growing bigger but i am extremely emotional.. i looked at his newborn pix and broke down and cried.. i wasnt this emotional with my daughter i think because i knew id have another child.. but we are not planning anymore so i think that scares me😩 even tho thats my choice it makes me really sad..maybe just a phase? How do other moms cope w this?
