I am not claiming that motherhood is easy (because I'm pretty sure there'll be a great number of violent reactions if I do). But motherhood should never be used as an excuse to feel homely. Remember, it is a crime to lose oneself while becoming a mom. That is why, it is very important to once in awhile have your "me time."
Let me share with you what I do (to each his own :D) to hold on to my identity while also being the mom.
