Nope, he won't starve. I do the same. DS1 is a terrible eater at dinner time. I am always worried about his terrible habbits for dinner. But I have tried everything reasonable and still he will not eat. I can often hear the water sloshing in his tummy. That give me the mummy guilts big time, but I refuse to feed my child biscuits/chips/lollies/whatever junk he comes up with the he wants for dinner. He goes to bed without having eaten since around 3.30pm if he has no dinner (bed time at 7.30pm). Thems the breaks.
