I replied to another post stating our pups were weaned at 6 1/2 weeks and was I ever fooled. I kept noticing they weren't eating the food much in their xpen the last 4 nights, then I noticed Dori's bags looking full again. So last night I got up at 3:00 and caught her in the pen with babies and they were just nursing to their hearts content..... She's not nursing during the day, just at night now. How long should I let this continue?? And I thought they were making it through the night all on their own
