Wait till the day you can see it from the outside !!! It's crazy.
I'm almost 30 weeks, and i've been seeing the big kicks for about 3 or 4 weeks now- it's not a baby in there, it's a foal, I swear !!!!!!
One of my freinds used to balance things on her bump, and see how long it would take for her baby to kick them right off.
I could do without it at night though, to be honest!!
