DS used to be a very hungry baby, easily taking down 6 oz formula bottles at most feeds for the past couple of weeks. But suddenly he's only taking around 4oz a time and not looking for any more. Is this normal? He doesn't seem distressed, and is not being sick or anything. I'm wondering if he's just cutting back as his growth spurt slows down. At 8 weeks he weighs 12lb 10 - he was born weighing 8lbs 10 and he is doing well on the 'chart', putting on the right amount of weight every weel. I'm just worried that he won't put on the right amount next week as he's taking much less food at the mo.
