I have used Frontline Plus for years and get good results. I have had to use Comfortis in the past with my now passed girl. She had no side affects from it. Comfortis kills adult to baby fleas, eggs and larva. When I had to use it my dog had a full meal, perhaps your baby needs more food in her stomach before Comfortis is given.
