Im not that it has much to do with the c/s but with Isabelle I felt movements at 21 weeks or so. After a c/s and with this pregnancy I was really worried because I didn't get any really big movements until close to 24 weeks. It is normal and everyone feels movement at different times, hard not to worry though I know. Have you had your scan recently?? Hopefully you were reassured while there hun. Hoping you are frequently booted soon!

ETA- Forgot to add that while this little guy isn't as active as Isabelle was, he still moves and squirms and kicks pretty much all day long now!
