Toddler only wanting to eat from mum and dads plate

Guys is this normal? My 20 month old daughter has always been served her own plate (same exact food we eat and same time we eat too). Her plate is almost untouched every single time. Of course we serve our own plate extra in case she eats from our plate as well but like she will not eat unless it’s from our plate also it seems after a couple of spoonful from our plate and she’s completely done and wants to go off and do something else. Idk if I’m just over thinking it but it definitely doesn’t seem like she’s eating enough 🙃
