This is just a suggestion.. don't want to step on anyones toes.
If you do have trouble remembering to give your babies their heartworm preventatives, their are other options to consider. I don't know if it is available in the US (as i live in Canada) but there is a 6 month heartworm prevention method called Pro Heart 6. it is an injection (given by a Veterinarian). You just have to ask your veterinarian about other options your clinic could offer you
Also, it is just heartworm prevention.. there isn't flea prevention in it, like some others offer.
Hope that helps.
