Huge congrats! How exciting! My girls are 15 weeks now and while that time has been one hell of a learning curve, there is light at the end if the tunnel now with plenty of smiles and giggles.
I had a planned c section and it couldn't have gone any better. One thing I did do from about 34 weeks was express and freeze colostrum and I really found it took some pressure off when feeding the girls before my milk came in. As a result, they are exclusively bf and have never had a drop of formula which would've happened had I not had that supply.
Good luck, has it sunk in yet?
