I remember DD's first movements at 17 weeks. I was laying on my belly with an aloe vera patch on my bum (I fell against the wood fire, resulting in 2nd degree burns on my bum. Quite funny, actually. Just shows you should pull your pants up a bit more before you crouch in front of a fire!!) and it felt like little pops in my belly.
I remember eating tea at night, something hot it was, and as soon as I starting eating I felt the little pops and flutters in my belly.
I remember stopping suddenly as it clicked in my head what is was. It was so cool to sit with DP and say "The baby's awake!".
