Breastfeeding advice

Hadley
Hi ladies!
I'm currently 20+5 with my second child and I want to breastfeed. I was was 17 when I had my first and I didn't even allow breastfeeding to be an option. Now I'm 25 with my second child and I want to give it a try. Any suggestions on pumps, bottles, classes or just general advice? 
Thanks in advance ladies !
