You need to figure out what works for you, and what you are comfortable with. You're going to have these types of pressures throughout your kid's life, unfortunately. I think a lot of times these "rules" are promulgated by people without kids who have no idea what it's really like. We had one pediatrician who told me we should take my daughter's pacifier away at 3 months, while another doc who had 3 kids was like "you do what you need to do to get rest. Get rid of it by 3 years old if you can".
