17.5 weeks (grew a lot this week)
And for comparison's sake: 17.5 weeks with C (the poor middle child doesn't have another belly shot for a few more weeks)
Baby is moving a lot now and is beginning to have an "awake and active" time. Usually right after my meals (or before, if I haven't eaten in awhile).
We find out the gender hopefully this week! The boys are still usually calling Baby a girl. We shall see!
