Not Feeling Myself

Has anyone else just not quite felt like themselves since having their baby? I’m not quite sure how to explain it.. I just don’t feel like the same person at all. I’m completely disinterested in my husband, and I feel so awful for that.. I still absolutely love him but I just feel so disinterested in him. Like the baby has all my attention. Is this normal? Does it stop at some point? I just don’t know what’s wrong with me..
