So, last night my sister-in-law's water broke. From what we've heard, she still hasn't gone into labor and I'm starting to panic and think of everything that could go wrong. Mom was a midwife and she says a delay of less than 24 hours is normal and no one else is freaking out and nothing bad has happened yet, but I'm already a mess. Please help me be calm! I'll keep you updated.
