I didn't know I was in labour at the start either. I actually woke DH up after about an hour and said "do you think that maybe you might want to get up because I can't sleep..." pmsl... that's what I said! He got up and about 30 mins later we called the hospital and what do you know, come on in you're having a baby. Wasn't at all how I was expecting it to feel so I didn't register it as labour. I felt just weird all day prior to having him. I also didn't have my show and my waters didn't break either. They did that at hossy. 3 1/2 hours from when I first couldn't sleep to him being born.
