I think that people who have had just the one so far, completley understandably, tend to think that two= X2 the massive shock and effort (hassle!) of the first arrival. But infact there's just an incremental increase in 'difficulty' compared to the omg wtf 1000% change in your life the first one brings! And, in our case, and I expect in most parents case, you suddenly realise you're ok at this baby thing, whereas the first tends to be far more stressfull/lifechanging/nervouse and self criticalc - although still great! This, for us and most I'm guessing, makes them progressively more enjoyable/manageable as babies (presuming all else is = obvioulsy ).
