I'm so sorry that Rylee's tummy is causing him problems. I'm just curious what kind of digestive issues he has? My little girl has tummy problems & I've been free feeding her & giving her very small meals about every 3 hours throughout the day. She eats regular food though - Royal Canin XSmall adult kibble & RC canned and/or Science Diet canned. I also added a probiotic to her diet - Purina FortiFlora. I give her a teaspoon of yogurt everyday at 3pm & feed human food treats like diced chicken, green beans, etc. Her feeding schedule & the probiotic have helped tremendously. But I'm not sure if her tummy issues are similar to Rylee's. She has intenstinal reflux & tends to vomit bile frequently when her tummy is empty. She also has a sensitive stomach & we have to be careful with introducing new foods. Regardless of the exact digestive issue, a probiotic should help somewhat. Good luck! I know how it feels when our little babies are not happy
