so I'm 4wks pp. had our second baby and hubby says he only wanted 2. that I should get fixed. I want more one day. I love being a mom. I think if we had more income and was more stable financially we wouldn't have just 2. I'm hoping to get through school in the next yr or two and start a better paying job and hopefully convince him to have a bigger family. I dont want so many kids I cant care for just a bigger family.
