What/when to stop supplements?

[Guest guest]

Quick question - my son has the first of several evaluations with the school

district on Monday, Sept. 20 for his transition to preschool (others haven't

been scheduled yet). This is probably the most important since it's the speech

evaluation. Currently, he is on 2 EFA, 1 EPA, and a generous scoop of NV. What

should we stop, and when should we stop them? Should be interesting as we

haven't stopped any of these to date since we introduced them (and there's a

part of me that hates to, though I know it's necessary).

Thanks in advance!
