Advice?

Anyone else feel completely terrified about your relationship/marriage after having a baby? My husband and I want a baby and have stopped using birth control and I’m very excited but every now and then, I start to get cold feet because I’m scared of our marriage changing, of us growing distant, of him feeling somewhat neglected, for lack of a better word. Is this normal? Are we really ready? Most of the time I’m so excited I want to scream, but sometimes I just feel so unsure about it!
