Confessions

The last time I visited the pediatrician, she told me to be careful from now on since the baby was learning how to roll from his tummy to his back. She advised me never to leave him alone because this could lead to accidents.
I tried to follow her advice. But last monday, I was not careful. Baby Boy had pooed all over himself and I tried to wash him on the toilet sink. After finishing I wraped him in a towel and put him down on my bed. The second I turned over to go and wash my hand, I heard a "bong", following by a scream. Baby Boy had rolled over and fell on the floor. I was so surprised and scared. I picked him up and soothe him as quickly as I could. At the same time I was checking to see if he hurt himself. Thank GOD, the carpet and the towel acted as a shield.
The week before that, I forgot to buckle up my baby in his carseat before putting him in the car. And then I drove on the highway for 20 minutes. My husband was the one to discover my mistake. I was shocked that I had forgotten something so essential.
The thing is accidents happen no matter how careful you are. When I was a toddler, I hurt my chin and needed stiches because I was jumping between the sofas in our living room and fell. My father was surpervising me and he even told me to stop. But I did not listen to him. My younger brother cut his forehead on his bedroom door while we were playing hide and seek when he was 5. He bled like a hog and cried more out of fear of the blood than hurt. The baby of our family, my other brother cut his toe badly when he put it inside the wheel of the mountain bike he was riding with his cousin. These are the few examples of accidents that happen to me and my brothers while we were under adults supervision. Kids would be kids.
I am scared for my baby. And I try to be careful. He is not crawling yet but I see him roll over and dive on my bed. Or while I pick him up he stretches his entire body backward. He likes to move around. He is very curious of his surroundings.
What will happen when he starts crawling, or walking? Should I be extra carefu, never leave him out of sight, or just tie him to me?
