Considering formula feeding 2nd baby

I have a 14 month old and pregnant with my 2nd. I have successfully breastfed since he was born and still am breastfeeding him. For me it was time consuming, and not at all convienient. I really appreciated the experience but I don't think I want to go through it all over again. Am I crazy or a bad mom for even considering formula feeding if I am perfectly capable of breastfeeding?
