you may be a little depressed, everything changes when we have children, we are tired, our body is still recovering, hormones are going buzzerk, and we are stressed. talk to your doctor about this it is probably normal
SOOOO normal but not healthy or good for you! I mean it is not going to kill you but for your mental well being you want to be the person you once were... and all of this speaking from experience..... My husband and I just had a conversation about it the other day but I am so much worse than you I push my husband away when he makes an advance. I have something going on right now that I am going to the gyno for tomorrow and I am hoping its nothing but my plan for action about my libido is to plan out some sex.... it sounds so mundane but I figure the more you do it the more you want it? I am also going to get more excersize.... I have really been lacking there and I felt much more like having sex when I was excersizing - I dont know if you do or not? but if not it might help.
Try to get a baby sitter once a month and get something you feel pretty in.... try something different like massage - or something better haha
being a mother is allot of work and life seems to become so regimented that sex is the last thing from yoru mind.... just make it a point to schedule it and eventually the feelings will return (I HOPE!!!) good luck and stay in touch
