Wow I thought it was just me....There might be an actual syndrome called the SAHM syndrome. Where the brain just mushes away. Well, for me I just started working again part time and realize something has evolved and I really am not the same person. I think It goes with the reality that all of my energy, thoughts, love, concern ect are with my kids. I really have a hard time focusing on anything else. I look at it like this: this is the part of my life where I live for my children. It is temporary. I commend you on staying social like going out with friends, reading books and getting your children out daily. A lot of SAHM's isolate and totally loose touch. I am not a rocket scientist but I hear the more brain activity you keep your mind in, the better. Have you thought of taking a class at the community college or something? That might reassure you that you can still use your noggin plus give you a night to yourself. Hope you have a Great Holiday!
