Are you possibly a stay at home mom? My baby is also 11 months and she’s done this 2-3 times now, I think sometimes she’s just tired of seeing me which is what I chalk it up to, she will come back around I promise! She doesn’t hate you and you’re not a bad mom
I kind of am going through the same!! My son is 9 months he'll be 10 months next week but he hasn't been wanting me much lately. He'll want to be with my husband more then me and I start feeling like he's starting not to like me for some reason
