I know I should not be worried about Nic's weight since my dr is not but yesterday right before his bath he looked too skinny. He has always been small but I think the last two months have really taken a toll on his little body. He has been sick on and off for 2 months straight and when he gets a fever (which has been a ton) he doesn't eat. So what can I add to his diet that is high in calorie but healthy? TIA!
