I am so sorry you are going through this
We had a flea infestation a couple years ago and it was miserable. I felt like I was a horrible mommy, but my pups didn't even seem to notice the fleas. Just stay on top of it... Bathe them with Dawn dish detergent. You have to drown those fleas! I would fill the tub up to their necks and scrub, scrub, scrub. We finally got rid of them and haven't seen fleas since... Good luck finding a job! I will be thinking about you.
