Do you think caffeine/sugar intake during pregnancy could effect your child in the sense of making them "overactive"?

So I haven't looked up on this, just in a debate with co-workers. For example: Both my co-workers ingested caffeine freely and had a lot of sugar while pregnant (co-worker #1 had a slushie and multiple sodas daily). Both of their children were very active in the womb (which is an actual effect due to caffeine/sugar as it spikes blood pressure) but what about after birth? Both babies (under 2) are very busy, super active children that are hard to get to sit still and always on the run. Thought?
