Breastfeeding help!

I am scheduled to have my son in just 3 short weeks. When I had my daughter several years ago I tried breastfeeding and was unsuccessful due to her having issues latching & milk supply. However, with her birth It was an emergency c section and they started feeding her from bottles before I even was able to see her so I’m wondering if that was a factor in it.. anyway this time around, I’m wondering if you all have any suggestions to hopefully make this successful? Did you use any lactation cookies, or anything like that to increase supply?
