I should think bilingualism would be rather an advantage. At least if  
the child has average to good linguistic abilities. (Scientific  
research does have a tendency to forget individual differences inside  
a population.) I grew up in a somewhat bilingual environment myself,  
as my father came from the upper class and my mother from the working  
class, with markedly different sociolects. Maybe this is part of the  
reason for my fascination for language.

BTW, what is the percentage of bilinguals among conlangers compared  
to the overall population?

OTOH bilingualism may be a necessary evil in a minority population.  
For example Breton today is losing its distinct phonetics because  
nearly every speaker is bilingual.
