Mother's guilt

I left my daughter in her crib at home alone and went for a bike ride with my son. he wasn't secured in anything i was just holding onto him and he was hanging in front of the handlebars. I had to find a bathroom and somehow lost my son. I looked frantically for a long time. I was afraid I'd never see him again. Eventually I saw a large group of people standing around including police. I figured maybe they had him. They did and i went running up to him and he ran to me too. i hugged and hugged him knowing that i was in a lot of trouble for loosing track of him. deep down i knew i had been irresponsible but i played it cool. the police told me that they would wait a few days to see if they were going to press charges. they left so i started to gather our things. my mom was there all of a sudden and i was crying to her about how guilty i felt but that i had done something even worse...leaving my daughter alone at home. we had to get home before my husband because otherwise he would find my daughter home alone in her crib. my mom was not mad at me at all. she helped me pack up and rush to get back home. we beat him home and he never found out what i did
