Cold morning!!!

My son finally went back to school today, he is in Preschool and he didn't show up since Wednesday because of the weather, I feel so bad for not taking him but since we have to walk literally the school is like a block away from my house, I didn't take him because it was raining and cold (if you are from California you know we went like 5 days straight with rain) and on top of that I always take my daughter with me because my husband works in the morning so I'm not leaving her alone of course. So he missed 6 days and I feel like such a bad mom 😣 and yesterday he didn't go because he said it was way to cold so I didn't take him. Am I wrong for not taking him for so many days?
