My baby weighed 3lbs at 11 weeks. At 14 weeks she weighed 4.10 and now at 16 weeks she weighs 4.90. My guess (not that it matters) is that mine will be 6 to 7 lbs when full grown. Her Mother was 8 lbs and her father was 3lbs. I know you get curious as to their fullgrown weight but it really doesnt matter cuz you love em anyway and weight prediction is hard at best. The chart is just a guideline and doesnt apply to every case. Jus love em and know that you are so blessed to have them.
