Being a baby !
source
My son is almost three years old. I help him mostly to sleep at night. Sometimes it's very hard for him to sleep. When he is in an other room I always check if he's playing safe games. When he's running outside I run with him to make sure he'll not fall.
I look at him and think sometimes "How hard is to be a baby". I mean babies without their parents or someone take care of them can't live. They are so weak and they need help.
I never thought like that in my life. Having a child for these few years I understand how much our parents did for us. We should take care of them when they get old just like they took care of us when we were babies.
