Fussy eater at home

[Canttakethe]

I have just spent half an hour trying to persuade DS (nearly 3) to eat his tea. If it's not the general beige freezer tea, he is not interested. It was a small bowl of cottage pie tonight. I tried leaving him to it, coming in every do so often to lightly encourage but nothing worked. DH took over while I went to get a shower. Came downstairs to see DS eating bananas and yoghurt. DH had caved and allowed him this without eating any of his tea. This doesn't really feel right. At nursery he eats almost everything put in front of him.

Please, someone give me the definitive answer 🙏

Eat as a family
Serve food in dishes, and let him choose how much on his plate
Serve the meal in its component parts so he can have plain mash and sweet corn if he wants but you and DH eat the cottage pie
Get home cutlery and crockery with his favourite character on or in his favourite colour
Chat at the table, not about the food, but anything else.
