Well the plant I wanted to put in it was the large baby that's on the side of my mother plant, it's just I was not sure if it was the same type, of soil you know like what VFT like... Bog soil, with nothing in it so to speak
Many thanks Wayne
I know this is 3 days old and you've probably moved with a decision by now, but re-using that soil should be fine, so long as it's something akin to the following -
Fine peat moss (as opposed to backyard earthworm dirt), 50/50 mix of peat/perlite or peat/sand, long-fiber sphagnum - etc.
Typically (and I said TYPICALLY, peat/sand-VFT-people

), flytraps are grown in the 50/50 peat/perlite mix and sundews are grown in a 50/50 peat/sand mix. The two mixes are basically the same thing - nutritionally-devoid soil.
I'd also consider the possibility that the soil may have killed your sundew, in which case it may kill the VFT...
Second consideration, if the "baby" is growing separately and has its own roots, it's okay to transplant in general. If it's coming up from the "mother's" rhyzome (or is right up against), though, pulling them apart may kill the smaller plant as you'll probably tear its roots.
