Hi, Tinkerbell had her babies 3 weeks and 3 days ago, I took them to the vet yesterday to start them on their deworming. They are so cute and healthy looking and active also, they can walk and play, the question is when do I start weaning them? What do I feed them??

I am so lost.....When do I start potty trainig them?? She still cleans them but I have noticed in the last 3 days they are soiling the blankets

Is this normal?? What should their "new envirioment" look like?? Please someone, the vet said as early as 3 weeks I can wean them, sounds too early to me, Tinkerbell still has alot of milk, although I have noticed she nurses less than before
