Ofcourse I agree with everything Robyn wrote.
My own personal opinions (and that's all- just my opinions based on MY experience and what I've read here too) on the questions you asked:
1. I am just wondering how much pain to expect since they will be going through a c-section scar and that the incision won't be small.
That all depends on each individual's pain threshold, the way they heal, etc but I will say that you shouldn't be feeling a lot of pain- if so, please talk to your doctor about it and don't be afraid to take pain meds when needed. You cannot heal properly and as quickly as possible if your body is expending energy dealing with the pain- you also won't be able to rest properly.
2. What is sex like afterwards and are you actually ready to resume it after 6 weeks?
That also just depends but not everyone is ready at 6wks. I would think especially with a c-section you might not but don't hold me to that. I'm only going by my experience with c-section deliveries and I wasn't ready for "relations" at 6wks after those. As for my hyst- it was vaginally and I still wasn't ready for that until 8wks post op. Don't try to push yourself, if you aren't ready at 6wks- you have every right to wait as long as you need to till you feel comfortable enough to do so.
3. Has anyone else felt like that besides me or is feeling the same way as me or am I just being silly?
Oh NO you are NOT being silly. I felt the same way. I have 3 children also- all very young (and btw- we are close in age- I was 31 when I had my hyst) with one still nursing. I worried mostly about what would happen to them if something happened to me. Their daddy is a wonderful father but there's no way he would know/could do everything to take care of his children 24/7. He's not a mommy- KWiM? So you are NOT being silly to worry like this- but please don't worry too much. The waiting is the hard part- when others say that it's SOOO true... you'll see.
