It's really neat to learn about my son's personality before he even is born.
For example, he does not like to be crowded. If I lean over too far for something or bend over to tie an errant shoelace, I get a nice swift kick to an internal organ.
He is like me and likes to sleep in. I never feel any movement before 9 AM, unless I dare to affront his personal space, then see above.
He is most active between 7 and 8 at night and I mean crazy busy. I don't have any idea what he is doing in there, but I sense he is laughing as he does it. So far, his activities have not kept or woken me up during the night, so I can't be as sure of what he does during those hours.
One of my pregnant girlfriend's baby is most active at about 6 AM, so she has taken to calling her Early Bird. She is a few weeks ahead of me and the kicks are so strong, they wake her up every morning, at almost the exact same time. She doesn't even set her alarm clock anymore.
I have read in pregnancy books that the schedule a fetus keeps in the womb is very similar to the schedule that the newborn will have out of it. If I am lucky enough to have a baby that sleeps in until 9 AM, I will be a very happy camper indeed!
