What Am I Getting Myself Into?

Yesterday all three of us here were sick with a 24-hour flu bug.  It was not fun.  Today we were all still a little tired and out-of-sorts. Consequently, the house is messy and the dishes haven't been done in a few days.  Something in the sink stinks but I'm too tired to go fix the problem.  This evening as I was standing at the stove trying to get some dinner made, with the house a mess and Lia hanging on my pants whining for attention and food, I realized that in a few short months I was going to be adding a crying needy newborn to the mix.  I suddenly wanted to cry.  What am I getting myself into?  I can barely handle life and housework with one baby.  Dustin will be here of course but he works and goes to school. I know Lia will be a few months older and hopefully a little more independent by the time baby comes, but still she is a toddler and she needs a lot of attention.  I don't know, maybe I'm just in one of those pregnancy-related depressed moments, but I really hope once the baby comes I can keep it together.  I am so excited to meet the new little girl, but so very nervous as well.  I hope I can handle this.
