I have to admit that after having 2 normal births I would love for everyone to experience what i did! And I am sad that a lot of c-sections are elected due to a social fear of birth and misinformation. Having said that, you sound like you have done your research and if you are aware of the risks associated with c-section and you believe that is the right choice for your family then you are making an informed educated decision that is YOURS to make, and no one else need impact on that, unless you invite them to.
Really, at the end of the day, no one MAKES us feel guilty, the feeling has to already be there.
Since you are making an educated and informed decision, this gives you a wonderful opportunity to lessen some of the possible negative impacts, and provides you the time to talk to your carers about breastfeeding, bonding, and recovery etc.
All the best to you - i hope making your own educated birthing choices allows you to feel empowered!
