Hi all... curio tell them to piss off. If both your Dts are gaining weight, even if it is slow, and you feel they are healthy, then sod the centiles and the growth charts. You know those charts are based on FF and BF babies so are not particularly accurate. E was off the bottom of the chart for ages and only gained 1-3oz or so a week for ages, but as long as she didn't lose, was pooing and weeing and seemed happy, then I didn't worry. Obviously if your instinct is telling you there may be something wrong, then follow the instinct and do't be too precious about exclusive BFing. It is not a crime to give them formula. But if you feel the BFing is doing the job then stick to your guns. Could you give them a feed in the night for a while? It seems like going backwards I know, but they will go 8hrs without a feed won't they, which is a long time at that age, and maybe they just don't realise they are hungry and sleep through it!?
