Girls, please calm me down, I'm leaving my daughter with dad and grandma for one day, she's 7 months old, I'm going to the city to get her teeth checked, I feel like a bad mother, I'm taking my son with me (he's 1.8 years old), yesterday I took my daughter out, got one tooth treated, husband says that the son didn't sleep all night looking for me, now I want to take him back, I know in one day nothing will change, anyway, it's so bad in my soul ?
