I'm expecting a baby girl this July after having a 9yr old and 11yr old. Just wondering if anyone's in a similar boat or have experience with it? Just wondering how the body handles labor and if the kids are a help or if it's harder on the older ones? I'm VERY nervous, more for my kiddos than anything!
