I think with bottlefed bubs they do tend to put on more weight than breastfed ... I think anyway!
With exception to Alexander the buddha piglet! LOL.
Welcome Ellsbells! Xander takes about 100mL every two hours, but that is breast milk (EBM). I don't think at this stage anyone would worry about weight issues.. I know I only get congratulated on Xanders' massive gains by the health nurses.
