firstly sorry for taking so long..have been ill.
Right to answer your q. As the kittens will now be around a month old, the best idea it to put mother and babies into a carry box and pop into the vet. The vet will need to weigh the kittens and then be able to treat them all.
bathing cats and kittens in human shampoo is never a good idea as firstly cats dont like water and secondly the shampoo may irratate the cats skin. Thirdly, the shampoo will not work against fleas except to make them smell nice!
The mother will allow you to move them as long as she is with them then there should b no problems. Good luck. Let me know how it goes.
