Am I alone? I need to know

I guess I am not alone. Almost all mothers feel bad each time they punish their children for doing things that they are not allowed to do coz it may hurt them and having a 2-year-old kid that is so active, two eyes are not enough to watch him. If I am the only one like this, please let me know.

My son, as a 2-year-old, he loves to explore anything. He easily gets bored and even having millions of toys around him is not enough to keep him entertain. I may have time to play with him but not 24/7 coz I need to attend to my personal needs too. I just can't watch him every second which sometimes makes me feel guilty coz I know I should be watching him so that he won't do anything that may hurt him or put him into trouble.

I guess I am too young for this and I am not mature enough to become a mother. I, honestly, wasn't ready when my son came into my life, but I whole-heartedly accepted him without regrets. I love him to death and I wanted him to grow as good person. And a part of me is telling me that I am not doing the right thing and one part says, just be yourself. But how would I know if I am doing the right thing? Do you ask yourself that too?
