Sorry daffy I am a bit late! I had this with the piglet too, and my placenta was at the front as well. When I went to the hospital to be monitored the baby had hiccups or so the midwife told me and I couldnt feel a thing.
Glad all is well and at least your daughter now knows that the placenta position will dampen the feeling of baby movements. No one told me this until I went to the hosp (in a bit of a panic) to be monitored, you would have thought they might have mentioned it, but hey ho, there you go, so long as mum and baby are well, that is the main thing.
