Help please!!!!!

Maria • I`m happily married, & I am a new mommy to a beautiful baby boy & with my new little girl. My life is now complete 💚💜
I noticed that after having my son, my breast are rock hard. I tried breast feeding him but he won't take my nipples anymore. I had to pump at the hospital but no milk was coming out. I tried to hand expression them but nothing is coming out. I had an emergency c-section. Is there any other way to get my breast to soften??
