My sister has two children. Her pregnancy with the older of them was not bad, pretty "easy" compared to her second one. Her second pregnancy, 8 years later, she was sick almost the whole time, just miserable. And baby #2 was a fussy, difficult infant as well. When #2, Em, was little, her Dad would look at her sometimes and say "Kid, it's a good thing you were the second kid, because if you had been first, you'da been an only child!"

Each pregnancy is different, just as each child is different!

Some of those who claim to "love" being pregnant have what someone I know calls "maternal amnesia" - just remembering the good parts, and choosing to forget the uncomfortableness, the inability to tie your own shoes - even if they DID still fit on your feet, and all the other not-so-fun parts.
