You're nuts but if nuts is what feels right for your family then go for it.

Are you sure that you're thinking isn't just a result of sleep deprivation? Now that I look back on the time that we conceived DS2 I'm quite sure that I was pretty much insane although still functional. Not that I regret having DS2 just that if I had been in charge of the little hampsters in my mind I might not have chosen to TTC. I'm eternally grateful to DH for putting his foot down about number 3.
