Child not eating at home or in childcare

Hello
we are having a tricky time with our two yr old toddler at the moment. They became ill last October, they had a nasty virus that seemed to spread, started with cough & high temp and then developed to vomiting and diarrhoea. Since then their eating just hasn’t picked back up, in fact it’s gotten substantially worse. It used to be the case that they would eat two hot meals at their childminders so I wasn’t too worried but now they are refusing to eat most things there also. Things I know they like, such as croissants, apples, pear, yoghurt, carrots, peas, toast, raisins and breadsticks are all refused. We can get her to eat breakfast but that’s it. At home they will only have plain pasta, when at childcare she will usually eat pasta in a sauce but it’s not a guarantee. Vegetables mixed in is a no no, the whole meal is refused. So no chance to hide anything. If asked what she would like I just get told ‘I don’t want it’ same at childcare. I think she would probably go for baby purée and packaged snacks but I’m hesitant to go down that route. My child will be three in June.
At what point does it stop being fussy and be something that needs professional attention?

Should say they do randomly eat things totally unexpected like cherry tomatoes and mushrooms so that’s why I’ve not pursued help earlier as I always thought it would just pick back up

I think if she ll eat purée, I would just give her that and slowly try to reintroduce other foods.

It is normal for young children to go through fussy phases with food and more hungry phases. Keep an eye on it. Are they small for their age / underweight / losing weight? Otherwise just keep offering a good variety of foods and try to keep meal times relaxed and fun and not pressurised - if they don't want to eat when offered food after a bit of encouragement, just say that's fine if you're not hungry you don't have to eat now. Then offer them something again in an hour or two. Just keep doing what you're doing and offering a good mix of safer foods and different options. You can't force them to eat, it is nothing you're doing wrong. I've had this with my children on and off over the years. If there are real concerns about your child being very small for their age or losing weight, see the GP for advice. But as hard as it is, it really is best to try not to make an issue / stress where food is concerned...
