I was under the impression that they didn't 'get' that food can fill their tummy until a bit later e.g.9/10 months.
But the last few days my DS has been getting very ratty around lunch & dinner time & it's not a nappy thing & not a milk thing (as he's usually had it not long ago), nor tiredness. Once he's in his high chair gumming around & playing with his food he stops gurning & seems happier.
Is it just because it's a distraction or is he actually at a stage now where he is demanding meals??
Maybe he loves the taste of food! My eldest DS loved his food from the start and the more flavour I added to his meals the happier he was. Giving your little one solid food to eat is the very first thing you teach them and hopefully they learn to love eating and find it truly yummy. It sounds like your DS is already on his way!
I was so excited when my 1st DS really got into his solid food as well!! I suddenly felt I had the freedom to be more adventurous with his food (and stopped worrying the whole 'weaning thing') and started giving him the same meals as me and my husband mushed up, he loved it and it made my life so much easier only having to cook one meal.
