So this is baby #3 - and each labor has been SO drastically different. My first broke my water and contractions which just felt like never ending cramping brought him into the world 4 hours later - my second had very predictable contractions that grew with time and I knew. He was here 2 hours after arriving at the hospital - this one has me with terrible cramps for hours at a time, sometimes contractions - they keep me up at night, but nothing is regular and then they just go away a few hours later. How am I supposed to know when it’s go time?!
