Do folks have any ideas on what foods will put pounds (well ounces) on a baby. I would like to fatten up my little girl (and no, I am not the witch from Hansel and Gretel) and was just wondering. Breastmilk does not do it for her. She stays active and thrives extremely well on breastmilk (too well for us to sometimes keep up with her ), but that babyfat is pretty much minimal. She's 50th ptile for height and 5th ptile for weight.
