Have a 25 day old go from 2.766kg to 3.15kg in 2 hrs, & then be consistent at 3.245kg? I'm not allowed to feed, only supplement. Birth wt 7.1.

Need more info. You didn't mention how long your baby has been at 3.245 kg. Unless your baby ate almost 13 ounces in 2 hours, it may have been scale error or a different scale. It's great that your baby is back up above birth weight, though! i hope your doctor recommended that you pump and store your breast milk. If your baby gains about 30 grams (1 ounce) daily, that's what we aim for.
