Angelique,
I have an anterior placenta also and i thought same as you a few weeks ago baby wasnt really kicking much that i could feel or it was very dull but im now at 26 weeks and my lil peanut is kicking me as i type funnily enough. it gets stronger by the day as i am finding and higher up am finally at the point where i can see the kicks and its such a wonderful sight it truely is i sit at night watching tv with my DF and hes never looking at the telly usually my top is pulled up and hes watching for the baby. Every baby is different some dont kick very much at all others go ballistic most of the day. so long as it is still kicking you can be happy with that alone.
Have a great day
Mel
