Totally normal phase. Keep offering without pressure, and serve veg alongside something they DO eat.

Ellyn Satter's division of responsibility - you decide what/when/where, they decide if/how much. Stops the battles.

Hide AND offer - both. We do grated carrot/courgette in pasta sauce and also a small portion of plain veg on the plate.

Mine went through this around 2 and came back to veg around 3.5. Hold the line.

Smoothies. Spinach, banana, blueberry, milk. They drink anything pink/purple.
