Your pediatrician is not giving you the best advice about this. Unfortunately, pediatricians don't always have the best advice when it comes to breastfeeding. The American Academy of Pediatrics recommends breastfeeding for a minimum of 12 months and as long as is mutually desired by mother and child after that. The World Health organization recommends a minimum of 2 years. So at 18 months - it is completely normal for you to be breastfeeding your daughter. My son is 2.5 and nurses 1-3 times per day. At 18 months he was still nursing 6-8 times per day. Don't let anyone pressure you into doing something that you and your daughter are not ready to do. You will know when it is time. And if your daughter really needs it now, then it probably isn't time yet.
You are doing a great thing for your daughter! And you should be proud of it.
