I think you should stick with what you are doing (weaning) but make it gradual. You don't want to give in and resent breastfeeding because it makes things easier. But there is nothing wrong with continuing either, just do it for the right reasons. If it isn't working for both you and your baby than you should probably wean. Nursing becomes a comfort thing like a special blankie or pacifier. I weaned at 10 and half months because I knew it was going to be difficult when he got older. I am impressed that you went this long working full time. I think she is being needy because she feels like something is missing. Are you doing anything to replace the nursing? Like extra cuddling, story book time, special bottle/sippy cup time, rocking her in a chair, holding her? Some of those things might help replace the nursing time. another thing to consider is that she may just be hungry, are you using enough formula or giving her whole milk to substitute these feedings? good luck!!
