Despite our best efforts to fatten him up, Quinlan did not gain any weight for the 2 weeks between seeing the GI specialist and the pediatrician. We were unable to get an appointment with our regular doctor for the weight check, so we saw another pediatrician in the practice. This doctor was quite humorous, stating that Quinlan's diet of steamed squash, beets, pears and prunes was what he ate when he was on a diet and suggested we add some protein to his diet.
He was not overly concerned about the lack of weight gain and suggested giving him more milk for his bottles and giving him legumes, yogart and cottage cheese. The cottage cheese did not seem to agree with him, and we are still trying the yogart. He LOVED the chickpeas that dad made up for him mashed with avocado and olive oil.
Hopefully a few adjustments to his diet will help with the weight gain. We swear he is getting longer though as more and more outfits get removed from the rotation as we are no longer able to squeeze him into them. Of course, Quinlan is super happy about the doctor's orders to feed him more and has been quite content otherwise.
