Re: Pediatrician advice?
Frankly, I think your pediatrician gave you advice so bad that it is laughable. 3 nursings a day and none at night? .
My pediatrician would tell you that until a year, breastmilk (or formula) should make up the majority of a baby's diet, and that until age 1, solids are just for fun. Three nursing sessions per day is unlikely to provide a baby with the majority of her calories. My pediatrician would also tell you that the transition to a majority-solids diet may be slow, with many babies not eating much solid food until well into their second year.
If you are planning to wean at one, you may want to focus on getting your baby to eat a balanced solid diet in addition to unrestricted nursing. Once your baby turns one, then you can start the weaning process, cutting one feeding a day until they are all gone. But if you are planning to keep nursing your child into the toddler years- something I highly recommend!- then there's no reason to try to whittle down your number of nursing sessions. Give it enough time, and your baby will wean on her own, I promise!
As for sleep, your pediatrician gave you parenting advice, not medical advice. If you are happy to nurse at night, there is no reason not to do so. If you would like to cut down on night-nursing, you can do that, too- but it's totally up to you. Again, it's a parenting decision, not a medical one.
