Hiya, my LO has always been a big eater, and never leaves a plate bare or turns down a snack, but recently he's been signing HUNGRY and FOOD for all of his waking hours. he's good at signing and communicating but if I fed him every time he said he was hungry I'd never stop! is this a normal thing, maybe a growth spurt? is he just testing the signs? I'm worried that he is actually hungry and I'm denying him food.
