hun, you are not crazy at all!
from beginning on, I had the impression that there was sth wrong with the birth I had!
I think our instincts as a mother tell us much more as we ever would have expected.
apparently, there was a problem with our LO's heart rate as well.
and, well the vacuum you needed at the end, could have caused the same problem that our LO has, that there is some built up pressure from birth still inside your LO.
if you are interested, google for cranial ostheopathy and you can read more about it. they say, especially assisted deliveries can cause problems, which can be treated with cranial ostheopathy.
for us, it really helps and we can't wait for our second appoinment tomorrow
ps: did you not say your LO wants to comfort suck all the time?
'cos ours as well wanted to comfort suck all the time, and I was stuck on the sofa for the first 3 month.
