Now obviously I know that if baby poops at night I will change it. My son is 2 1/2 months old and is no longer pooping at night. I also know that if the diaper is full I should chane it to avoid leaks. My question really is about comfort for the baby and cleanliness. Like, do you just have the attitude that if the diaper will hold it to let them go and not bother waking yourself up to change a diaper? What is your "policy" for that?
