would this be your deal breaker?
I am 29, have been married for 8 years and have one 2 year old daughter who was a micro preemie. As with most 2 year olds my daughter is a lot to handle and my husband works 15 hr days 6 days a week. the fact that my 2 year old drives me crazy has my husband telling me that another kid is out of the question. We owned a business throughout my pregnancy and until my baby was 1. I feel like it's unfair for my husband to deny me another child! I didn't really get to experience pregnancy and the newborn stage, breastfeeding, etc. I don't want my daughter to grow up in 2 households but I am really not seeing how I can stay with him if he wont agree to at least one more kid.
ETA: I really feel like my child would only benefit from a sibling, I am the oldest of 6, and I feel like she would be so lonely without ever having a sibling.
