My DD is almost 13 months, and we were BF 4x a day. Then out of no where she would start screaming, unlatch, and want her paci. I though, maybe it is teething, well now 2 weeks later she will walk over to me put my nipple in her mouth, and nip me, smile, and walk away. Is she done now? We still nurse first thing in the morning, but that is all she will do, I offer at the times we did nurse, and she will try to get back up, or will do the nip/smile thing. Ideas?
