Toddler being mean to me when I’m 8 months pregnant I’m crying

He doesn’t seem to want me around. He wants his dad to do everything and doesn’t seem to even want me touching him.

I am 8 months pregnant, and I don’t know if that’s it? He knows his brothers name now and will touch the baby and kiss him so he clearly knows it’s a baby. I don’t know why else he would be so mean to me. I am trying to be an adult about it but he is my baby boy and he doesn’t understand it won’t be just us ever again.

I don’t know what to do or what I’m doing wrong. He won’t even let me get him dressed
