Our 2YO son was eating very selectively, and we worried he's eating too little. I thought about it. And I realized we place too much importance on him eating by encouraging him to eat. I said to my wife: you know what, we remove this importance totally. We don't tell him, ask him, encourage him to eat anymore. If he wants to eat, he can eat. If not, then not. Guess what happened? He's now eating satisfactorily. But not according to our schedule or exactly what we cook. According to his schedule. I also started asking him in the supermarket what he'd like to eat this evening. Then he points at particular things: broccoli at one day, chicken filet at another day, pickled cucumbers, etc. And guess what? He absolutely is eating what he picked earlier. Very instinctively to what nutrients his body wants. Maybe this helps other young parents. Stop putting importance on it.
