I usually have my whelping box in the spare bedroom and I sleep in tehre for teh first 4 - 7 nights (depends on the dam, teh size of eh litter etc). Then I move back to my own room
At around 3 weeks old I move the babies to my dining room with easy access to the outside and ongoing interaction with people, dogs, noise etc. Studies show that the most critical socialisation period for pups is 3 - 12 weeks so I do not want to miss any of such a short window.
