Not in the least true here. Didn't decorate a nursery for my first until it couldn't reasonably be described as a nursery any more - she was four. Didn't have a cot until she was 7 months. I do a lot more exercise in pregnancy than I used to. Certainly think about being pregnant 10x more. And find it a lot more worrying.
Though I did lose my 1st and 3rd pregnancies so maybe it's not aimed at me.
