Right on, BSS!
The Baby Tears (Hemianthus micranthemoides) you have growing must be under good light.
I have found that when I have Hemianthus micranthemoides under high light, the plant begins to grow low and creep along the substrate. While it forms a really nice carpet, it doesn't work if you want the plant more upright like a bush.
Since "Baby Tears" is a common name and not a scientific one it is hard to know for certain which plant you may be referring to. A photo would help. If you are looking for a very similar plant with a more upright habit under higher light, you may want to look at Micranthemum umbrosum.
