Anyone else struggling to get their 3 year olds to eat meals?

My son is the same but will eat chips and pizza. But those are the only meals that arent a fight.

We have started the 2 bites method (at least thats what my mum calls it). They must eat 2 bites of whatever dinner is, then they get their choice of other food. Until those 2 bites are in and swallowed! They dont get their chosen food. [Obviosuly for foods they 100% dont like e.g. Brussels sprouts, this does not apply. I am talking about meals I know they eat because they have it at nursery with no issues]. We have also now escalated at time to removing all toys/screen time until those 2 bites are eaten to get him to cooperate, he is extremely willful. But as soon as he does he gets everything back as a reward, even if it had taken an hour to do it

Honestly we’ve basically had to stop the snacks (other than 2 snacks a day which she chooses in the morning and has at mid morning and mid afternoon). We offer a safe food that we know she will always eat alongside whatever we are eating and if she doesn’t eat anything that’s fine but when she is hungry later on she either gets what was offered earlier for dinner or she can have some toast

Most basic thing ever that I found works. I say “you need to have at least (number) spoonfuls”. She likes the game of it. We quickly go from “I don’t like” to counting. Then I challenge her - “try 3 more! And one for luck!” Etc
