I'm at the end of my tether with DS2, who's nearly three, and eats a proper meal perhaps twice a week. For breakfast he will only eat half a brioche roll with Nutella, while for other meals he might condescend to eat pasta, rice, sausages, steak or lentils, with plain yogurt, broccoli or carrots, but only about once a week will he actually clear his plate. The rest of the time he demands spaghetti instead of penne or sausages instead of steak, and has his grandparents (they look after him Monday to Friday) dancing around him producing meal after meal in an attempt to get him to eat.
I don't do this - he either eats what he's given or has nothing - but neither approach seems to be working, and he's lost a lot of weight over the last fortnight when we've been on holiday (when it's been very hot, and normal routine has been disrupted) and he has lived on milk, ice-cream, chips and bread. (The last time he was weighed he was on the 78th percentile (91st for height.)
He seems to have a limitless capacity for crisps, chips, biscuits, chocolate and breadsticks (which I try very hard not to indulge, especially in between meals, so that he doesn't fill up on crap), so clearly he does feel hungry but he just isn't interested in proper food. His brother is an adventurous eater, interested in how dishes are made, and how things taste, and is a joy to feed but I'm finding mealtimes with DS2 absolutely horrendous at the moment, and I just don't know what to do.
