Re: Baby doesn't want cereal...
It sounds to me like she just isn't quite ready for solids yet. Can you remind us why your pediatrician recommended starting cereal? Is s/he concerned about weight gain or just thought it was time to start?
If there is a weight gain issue, maybe you can just try to encourage more nursing to increase intake rather than solids. If the ped just felt it was 'time to start' I think it would be ok to follow your instincts and wait if you don't think baby is ready.
