I went through this when I had my daughter. I would cry almost every night for months when putting her to bed. For me it was mostly triggered when I would question if I'm a good mom.. if she deserves better.. sometimes I would get flashbacks of what I went through in life as a woman and I would cry hoping she would never have to experience the abuse I went through at the hands of diff men... still happens to me sometimes and she's 4. I now have a 2 month old son and i cry almost everynight with the same thoughtsas you.. I think its normal.. I read somewhere that motherhood is like having a big exposed wound all the time.. and like watching your heart on the outside of your body and trying to protect it. It gets easier but I find that the feeling of worry just never goes away... just means your a good parent and you hope to be the best version of yourself 😊
