I wonder whether General Mills, Kraft, Nestle's, Oscar Mayer, McDonald's, Enfamil, Gerbers and a few hundred other companies that make and market foods to children would agree.
Actually, the "foods" part does make sense; you often see headlines like "The 5 Foods That Keep You Slim". But the .net hurts this domain a lot - that would reduce any interest from companies like the ones you mentioned. So I'm afraid I see little value here.
It's okay to use kid as an adjective if you want a colloquial (informal, conversational) usage. For example, kid brother and kid stuff are commonly used.
I see two grammatical errors in your postIt's okay to use kid as an adjective if you want a colloquial (informal, conversational) usage. For example, kid brother and kid stuff are commonly used. Given the subject matter, I think the colloquial usage is fine. You wouldn't want to sound too formal in this case. Also, kidsfoods doesn't work sonorously. Too much sibilance for the long "o" sound to carry. The sibilance works better with the short "o" sound, however, in kidstoys.
In any case -- though I understand your hesitation if it doesn't sound good to your ear, and I personally object, under most circumstances, to ungrammatical usage -- the greater question is not whether the domain is grammatical but whether it is marketable.
By the way, you have three errors in your first two sentences. Two punctuation errors, one of which also results in a usage error, and a grammatical error.
Sorry about that! Under the circumstances, the English professor in me couldn't resist.If anyone ever has grammar questions, I'm your woman. But truth be told, in a forum setting, I never bug people about their grammar and punctuation. Except today. Besides, I'm a lousy typist and make too many typos to criticize.
