At what age do you worm kids for the first time with Ivermectin paste? Also, today we gave the kids their first CD/T vaccine. On the last kid, she jumped and at least 1cc ended up on her fur (out of the 2cc's). Would you recommend re-doing it with the full 2cc's, giving her just 1 cc, or doing nothing. It was my fault - I didn't have her braced well enough.
