I was wondering how old is your baby? I bought a bag of Nature's Variety Instinct for Mocha but haven't fed it to him yet 'cause he still has a couple bags of his raw food left. I was going to start him on it after all the raw is done. But now I'm a little worried since you mentioned that she grew taller and heavier in a just week. Mocha is a little over a year old and pretty much full grown, but I'm not sure if this will give him a major growth spurt all of a sudden? I don't want him to get any bigger, but only because he's got such a tiny little frame and tiny bones, that if he puts on excessive weight I'm worried his tiny frame won't be able to carry/support his weight. I just read a post where a member was saying her baby's ribs got seperated because she had put on too much weight for her tiny little frame
