Oh goodness...not again

I get on baby kicks. I go baby CRAZY and it usually lasts a couple weeks and then I get over it. During this, I forget about my plans and the order in which I have always wanted to do things. College, work for a few years, travel blah blah blah... I think getting married, buying a house, settling down in a career, having two dogs makes me forget that I am only 21 (22 next month!). I feel much older. Right now this is the worst baby kick I have ever had. It has lasted much longer than a few weeks and I am scared that it will never go away!!! What if my priorities have changed? This would not be a good thing because my better half has not changed his..
When you decide to have kids its about making the transition from married couple to parents. It's about suddenly dedicating a huge chunk of your lives to this beautiful little creation. When you have a baby, you are not just creating something to cuddle and to fulfill the requirements on the biological clock, you are creating a person. This person will have wants, needs and desires. Does any women really know if she is ready for this responsibility?? How can you really understand the rewards, the frustrations, the anxiety of parenting until you are knee deep into it? Hindsight is 20/20. Perhaps it is only later, when you are looking back, you know whether you were ready or not.... Hopefully, I will just get over this.
