do you cut them in half? I've been giving DS chewables for over a year now and just realized the dosage for a 2-4 year old is half a tablet. I just assumed that if my ped said I could now give the chewables that 1 chewable vitamin would be what I would give...bad mommy I know. How the heck are you supposed to cut them in half anyway? I give the CVS chewables. Maybe I should check another brand? And how bad do you think it is that he's been getting too much vitamins?
