Snow - rest be assured that research shows that it can take introducing a child up to 30 times to a new food before the child will show interest in it.
Try not to fret and keep meals low keys. If he eats, great, if not oh wells... he will eventually. They say babies and toddlers can pick up on a parents frustration and then use food as a battling ground.
Dex is a great eater, but there are still certain foods that I offer that re doesn't want to eat so I just let him leave it on his plate and don't say anything about it. Currently he loves all veggies and fruits but pickles and raw tomatoes.... but he wont eat breads. So I just keep offering a piece of bread in different ways on his plate and if he takes a bite, great, if not great. It's only a matter of time.
