I am only five weeks pregnant and already I feel protective of my baby, so much so that I want my co-parent around less. Is this normal?
It is normal, your body is going through so much change at the moment and your mother-instinct is trying to kick in fully at this stage. Your hormones will be rapidly changing, causing so many mood changes, protectiveness, etc. Things will fall into place but it is normal for you to be feeling this way at the moment.
