I'll try and keep this short.
When I was 19, I had my daughter. Her father and I separated but get on well. When she was 5, I married a great man and we have had a little boy. Whilst juggling being a mum, I've also got a good job and I'm in university training as a RN. My husband would like a 3rd baby, and I don't. I struggled with PND and had a hard labour with our son. I've been a mum nearly 10 years now, and I finally feel I am at a point in my life where things are getting easier and I am doing something for "me" as I enjoy my job and my training. Am I unreasonable not to want to have a 3rd baby? I'd struggle with childcare/bedrooms/extra finances. My husband sees it as company for our little boy when my daughter is at her dads. That makes me feel guilty for saying no.
