Assuming both baud and wuf are staying quite close to their mothers, and their mothers aren't too close to each other, then yeah, I guess.
Given the high probability that they both spend an inordinate amount of time near each-other's mothers, though.. it's probably a wash.
As Renton correctly pointed out, though, the effects would be so slight as to be immeasurable.

I don't have a 'rule of thumb' for mass-based changes in the relativistic factor. For velocity-based changes, effects are usually immeasurable for speeds below about 0.2c or ~60,000 km/s (~134,000,000 mph). At that speed, The relativistic factor is ~1.0206. This means that time is dilated by ~2.06%, space is contracted by that factor in the direction of motion, and mass is increased by that factor.
fraction of c || relativistic factor
0.1 || 1.0050
0.2 || 1.0206
0.3 || 1.0483
0.4 || 1.0911
0.5 || 1.1547
0.6 || 1.2500
0.7 || 1.4003
0.8 || 1.6667
0.9 || 2.2942
0.99 || 7.0888
0.999 || 22.3663
0.9999 || 70.7124
You can see that the relativistic factor grows slowly until ~0.5c, and then rapidly above 0.8c.
Notice that something traveling at 99% the speed of light can cover over 7 light-years of distance (in an outside observer's reference frame) in about 1 year's time (in the traveler's reference frame). This is not a violation of the speed of light, it is the consequence of said speed limit.
