It took a while for me and the misses to get back in the saddle again. She probably had discharges and sensitivity issues down there for a bit afterwards. She may feel insecure about her body now if any baby fat remains. You should talk with her, hold her, love her, and tell her how sexy she is to you. Women go through various levels of post partem depression and with women, generally if it is not all 0kay in their heads, their bodies don't respond well either.
Good luck
