13 month old just not eating for me

[Ineedsleep2024]

Hi all, my DS 13 months has just stopped eating for me. He will only eat 2 things: weetabix and peanut butter toast.
He used to be a pretty good eater but that has stopped in the last few weeks. I am lucky if I can get a totally it 1 teaspoon of food in him on my days with him.
So far I have tried: always eating together, offering the same as mum and dad, offering off of my plate. Nothing is working. I’m 99% sure he is just testing a boundary as he will eat for granny and at nursery.
I guess I am just asking is this normal? I’m trying hard to not just offer things I know he will eat, otherwise we will just get stuck in a loop but I also don’t want him to be hungry!
any advice?

Cut his milk right down and start offering what you are eating with a tiny portion of something you know he likes.

I wouldn’t make a big deal out of it unless he’s particularly slight. Just feed what you’re eating. Don’t give in and offer weetabix otherwise you send the wrong message etc eventually he’ll see alternatives are t forthcoming.

Thanks that’s reassuring. He’s already down to 1 210ml bottle of cows milk before bed only.
Im really struggling to not cave as I don’t want him to be hungry but also I don’t want him to only eat weetabix.
