Dear friend,
I am sorry your babies have all this trouble. Yes the little white things are tapeworm segments and related to the fleas.
I am also sorry your babies are troubled with fleas. You dont need any harsh products.
All you have to do is put down some Diatomaceous earth in your yard and a few pots in the house and you and your baby will never see another flea, fly, worm, etc.
Get it at a garden shop or online:

I am in Florida where fleas/bugs/worms are active 24/7/365 and it works like a charm for me.
I hope your babies get relief very fast.
Best wishes,
