We are expecting to adopt. Baby boy is due in June

I met with a lactation consultant to see just what would be involved in breastfeeding. Maybe I need to talk to women who have actually done it, but it just seems impossible to me to pump as much as I would need to for the milk to come in before baby gets here and so cumbersome to use the SNS after the baby gets here to do it that way. I guess what I'm saying is it seems too overwhelming, but at the same time I feel guilty for not doing everything I can to give my baby the best. Any advice?
