My baby is 10 months old and my boyfriend and I share the care of him (we live together and both work part time over the whole week.) Over the last few weeks it's become pretty clear that my baby prefers his Dad, but in the last week it's stepped up a notch and he refuses to have anything to do with me if his dad is there too. He cries if I hold him, reaches out for his dad, cries if I make eye contact and now has started arching his back and throwing himself back if I try and pick him up. This is beyond hurtful to me and I'm struggling to get past it, I feel like the worst mother ever. Has anyone else ever had this and got past it? I don't know what to do.
