Movement from outside

cara117

I'm about 18.5 weeks along and the only time I can really feel movement is when I lay on my back, and put my hands on my belly, and when the baby kicks I can feel it from the inside and the outside.  I don't really feel it any other time though, only when I can feel on the outside too.  DH has also felt it from the outside.  Seems kind of backwards to me, anyone else have this happen?
