pacifier question

Na

My little one will be 10 month old this week. She has always been a thumb sucker, we tried for the pacifier when she was younger but she had no interest. She discovered a pacifier yesterday and used it all day. This morning she spotted it on the coffee table speed crawled towards it and put it in her mouth. She is working on her top teeth right now so is it just a teething thing. Should I encourage/discourage or just follow her lead?
