G.,
First I would like to say that I felt that way after the birth of my second child. I have a 4 year old and an 8 month old and I didn't get much "help" once I got home from the hospital. I knew that I loved my children but weeks, actually years of taking care of my oldest and then a new born virtually by myself made me feel like I didn't want to be a Mom or a Wife anymore. I BATTLED feeling disconnected and the feeling came and went. I cried and felt ashamed that I wasn't overjoyed to have baby number 2. I couldn't understand why I wasn't happy to wake up EVERY 2 hours to feed a baby that had trouble latching on, change diapers 10 min after that, and consol constant crying, missing and skipping meals myself, getting No sleep, cooking and cleaning after a c-section, actually seeing myself as approaching 30 and dealing with marital problems...I just couldn't identify with women who said "It's all worth it" like I had with my first child. These moments came and went. I constantly reminded myself of the joy I felt when things actually were calm, and pushed past exhaustion.
I'm saying all of this to say YOU ARE NOT ALONE, DON'T BE ASHAMED. Sometimes circumstances, hormones, a sense of loss of your freedom can set in after you have a child. Sometimes even after the child is older. Not all women are the same. Not every woman has motherhood on her agenda and go through this while other women wanted children but just didn't know what to expect.
I think we all have our moments, however if this feeling last longer than a few minutes and you can't get past it or if it is affecting your ability to care for your child then you should seek help immediately. Let your spouse, friend, parent someone you trust know how you feel so they can relieve you for a few hours each day. Also, talk to your doctor or pediatrician so they can direct you to support groups and medical help because this could be post partum depression, a hormonal imbalance, depression, anxiety, or any number of problems that can accompany a change in life.
We can chat if you like...or anybody else feeling like this...sometimes that helps too.
We mom's have to stick together for our children's sake!
