Are 50/50 for having another boy...
1/2*1/2*1/2*1/2*1/2*1/2=0.15625 or 1.5625%
We beat the 3% chance odds of having Willem Ellis as our fifth. So I'm not getting to cozy with the idea of a girl by 98% consecutive odds. ;) Supposedly the 50/50 shows up more clearly the greater the number...so if we had 1000 kids...it would get a lot closer to even around here. ;)
We could find out in two weeks...but we may go for the big bang surprise...if I can hold out when the tech asks if I want to know. I'm pretty sure Luke's motivation for waiting is holding my spending at bay if it's a girl. ;)
