Breast feeding


Ok so please no negative comments. When I first had my baby I was breastfeeding but also had to formula feed at the hospital bc she didn't urinate the first 24 hours. After a few weeks when we got home I got selfish and starting smoking cigarettes again so i stopped breastfeeding completely. Well I feel horrible. I want to try breast feeding again even if I still use formula so at least she is getting the benefits of my milk. I was wondering if anyone has stopped and then started breastfeeding again? Any advice would be appreciated. Thanks!
