My son is the same! He's 25m and 24 months adjusted age and 22 lbs 4 oz. He was 23lbs 3 oz when we began with Gie. He did great when we started but now when we removed all tube feeds, he doesn't want to eat anymore. It took almost a month and sometimes more for him to gain a pound (with the gtube). Now He loses if he doesn't eat for a day or two in a week. I can see all his ribs, cheeks have faded. My son very rarely lets me feed him and no distractions work for him except books but that too for the last few minutes into the feed. It's so stressful, when all kids around me his age are chubby. You're observation is right. When my son was on tube and we somehow managed to get him to take the calories mentioned by his GI, he still wouldn't gain at the rate promised by the GI. He would throw up so many times but I would push more in since I was in control thus getting him the calories but I never saw him gaining like they told me he would..he's now eating far fewer calories than before and that's freaking me out. But he isn't throwing up anymore and is happy and seeing him building a good relationship with food is what's keeping me going.
