Am i the only one?

Rye
Am i the only mother freaking out? I was excited about my son but now im starting to panic realizing our lives (mine and my 8 yo daughter) are about to dramatically change. Its just been us for so long and i haven't had a baby baby is so long what if I'm not as good with him as i was with her? Shes so excited but im scared she'll feel like im not paying her any attention once he's here. I have a good job but suddenly im freaking about finances and every thing else. Is this normal?
