Mixed Emotions!

Ok as the time draws near and I am about to have Carlie, I can't help to have many mixed feelings. I am anxious, curious, excited, scared, nervous, sad, happy, and the list could go on. Why should I be sad?? I am sad because I am so scared I am going to let Aiden down, he has been my "baby" for the last 2 1/2 years and I spend every minute I can, watching him learn and grow, and playing with him, singing with him, reading to him and just having so much fun. I have so enjoyed have me and Aiden time and I am so scared I will not be able to give him all he needs. Am I crazy for having these thoughts?? Please don't get me wrong and think I don't want another child, I am excited to see Carlie, happy to have a second child that will grow up with Aiden and hopefully they will be best buds and great friends. Happy to see how much joy she is going to bring to our family. I love my little man so much and our "along" time is fixing to come to an end and it really upsets me, and I finally broke down a little tonight at my Mom's talking about where he was going to stay while I was at the Hospital with Carlie and talking about I needed to get his bag packed. I have tried staying strong and tonight I couldn't hold back, finally I broke and it felt good, since I have kept it bottled up inside of me. Aiden said "mommy why you crying". He is such a sweet and loving child. I hope these feelings are normal. I am so anxious to see and hold my baby girl and I can't wait for Aiden to see and hold her, he has been asking me forever when Baby Sissy was going to come out. He talks to her all the time and tells her to come out and play with him. He always rubs my belly and kisses it. He is going to be a great big brother. He will teach her so much. He means the world to me and I know my little Carlie will to. I hope I do not fail either one of them and I hope I can give them the best. I love being a Mommy and I know having two children will be an adjustment, but it will be the best adjustment ever. Please pray that I stay strong for the both of them as we adjust to the changes that are fixing to happen. I love my babies and I am so blessed to have each of them in my life.
