DS (6 months) has moved down two percentiles in weight.
His intake of milk has been the same - about 27 ounces a day - for a long time now (FF) and I can't get him to take any more.
He is just starting solids (though not taking purees or anything from spoon so it will have to be BLW).
He is very active (full on crawling and climbing since a few weeks ago) so probably burning up more than he takes in. Why isn't he hungrier though, if using more energy? And how do I stop him from slipping further down the percentile graph? (I know the graph isn't everything but he looks increasingly slender too). He's medium in height.
