DD1 partied up a storm inside me. One night she kicked as I was spooning DP and he felt it quite sharply. Even my ob said, "you have a very active baby there." JUST the same when she came out. Never, ever stops but she's a GREAT sleeper, always has been, so it has its ups. We say her philosophy is, "play hard, sleep hard."

DD2 was so quiet in comparison that I went to the ob twice concerned that she wasn't moving. She was fine. Sure enough, she is much less full on though that could be me projecting too as she's only 9 months old. But she is very happy playing on her own compared to DD1 who would just follow me around the house and when she wasn't following me she couldn't be left alone as she'd climb. Found her on the kitchen table before she could walk.

So in my case, it was quite true.
