Hi all, long time lurker and first time poster!
My son was weaned early under advice from HV and Dr because he was drinking 40-50oz of milk a day.
He is a really good eater, eats literally everything and often has seconds or more. He is on 3 meals + snacks.
But recently he's just not eating his food. I'll put it down in front of him and he just won't touch it or thrash his head from side to side if I try to feed him. We go big on praise when he does eat, we've tried a huge variety of foods including his favourites but he'll only really eat berries and cheese strings at the minute 
he will sometimes have quavers or Ella's kitchen snacks too.
We've also tried to change the settings, in his high chair, a picnic, in the living room etc. We do have our evening meal together at the dining table and he'll just sit there not eating.
Any ideas on what to do?
We're raising him vegetarian if that makes any difference, I don't think it would.
