Well calcium doesn't make you fat so I'm going to assume she doesn't really know what she's on about, and assumes you're feeding him crap. As soon as I read he isn't walking yet, well bingo. Once he's running around he'll likely lose some of that lovely baby fat. I hate charts and all of that, there has to be healthy kids on all levels of the chart for it to even exist, and even off the charts there are healthy kids. Humans aren't one size fits all. I wouldn't be worried at all. Also, the suggestion of less everything more fruit is a bit silly, seeing that consuming too much fruit can be just as bad. Eh, I think DS2 is fine personally, I'd take what the MCHN said with a grain of (delicious) salt.
