I was so determined to breastfeed as well and it really helped to have the support of the people around me, it never crossed my mind to put him on the bottle and we've exclusively breastfeed since he was born! I also found the aba a great resource, I had mastitis early on and got lots of helpful advice from them. Good luck and enjoy, it's the most amazing and rewarding experience!
Just saw you're due any moment, sending you labour vibes!!!
