1 year old fussing and not eatting

So my 13 month old daughter throws a fit when it’s time to eat. She will then proceed to throw her food on the floor and fuss. The odd time she will eat a couple handle fills and then start fussing. It’s very frustrating and worrying as I want to make sure she is getting all the nutrients she needs she will have her snacks cracker,fruit some veggies, granola bars thing like that when she’s not in the high chair. A month ago this wasn’t going on sometimes she wouldn’t like something and not eat it but she’d take something else and be fine. I know time is limited when baby is in high chair but 9/10 times I put her in an befor I can even sit down to eat she’s fussing. Help any momas in the same boat? Also I know it’s typical baby/toddler behaviour but she will eat something one day and hate it the next, she also refuses to eat/try meat...I need advice pleaseeee
