I hear you on the in-laws thing. I have a thread on hear in the punching bag room called 'I'm too lazy' DP's Uncle told me I was too lazy to push out a baby thats 'normal' size (funny though Tristan was 6lb 13oz, bigger than I was and I was term) and thats why I have them early. Father-In-Law has also made comments aong the line of, I wouldn't know what 'true' labour was like because Brendan was so small.
Some people just have no compassion at all.
