I agree with the water - I think it's always important to have that available!

In principle however, I agree with the thing about holding out the food until the next meal time - it's not as if it's days away after all, just a few hours IYKWIM? We've done this with Jacob too and if he still doesn't eat or mucks with the food, then we take it away with minimal fuss on our part and just play the waiting game again and try not to give in to requests for inappropriate things like biscuits! We figure that if he doesn't eat at his mealtime, then he clearly isn't hungry. Some days I swear he lives on fresh air!!
