Girls, my husband left for work (shift). He's been gone for two days now. Every time I see him on video call or hear his voice, tears come right up. But only for 30-40 seconds and then I calm down. I don't know if it's because of hormones or if I can't get used to him being in another place. Now I wonder if it's harmful to the child or if I'm going crazy.
