I have week old pygmy triplets. They are all happy and running around, but I weigh them everyday to see how much weight they are gaining. Two of my triplets and one single baby have all gained 21-25 ounces in the last week. One of the triplets has only gained 15 oz. That's almost half a pound difference in a week. Should I be worried? I have seen mom (Symphony) nurse all three of them, but I only saw her nurse the bigger two today. The udder on the single mom (Tori) is actually larger than Symphony's udder, so I was wondering if it would be worth my while to force Tori to feed the little one once or twice a day? Or would it be better to make Symphony? (I did today with Tori and that is the longest I have ever seen a baby eat without stopping.) Or should I not be worried yet? Any thoughts?
