Baby energy?

During one of the baby classes we went to, the instructor said an early sign that the baby is near comes a good 10 weeks before the due date. According to the instructor, the sign is that the mother gets a big burst of energy she uses to "nest" ... get everything just perfect for when the baby arrives.
Where's my burst of energy? And is there a risk of baby "nesting" energy being "wasted" on preparing the house for family coming over for Christmas?

Amanda has had additional energy, but she's planning Christmas events and baking Christmas cookies galore. I'm not sure if I had any additional energy, but it was probably all used up to recover from feeling like garbage over the past weekend (half sick for the whole time).

With all this going on, who has time to remember there's a baby coming? (OK, that's very much a "dad's-eye view." I imagine Amanda can remember the baby is coming ... especially when he tests out his stiffening bones by kicking with more strength every day).
