Is it just my child

My child has never been a great eater for as long as she's been eating food. Always been fussy and pretty slow at eating. Recently she's got a bit better with trying different foods but she takes sooo long to eat, I mean like she needs a minimum of an hour to eat any meal (even when it's basic fish fingers and chips) i get when she's trying to new things it may take a bit longer but no if I give her pizza she will sit for atleast an hour ! Bearing in mind I'm not giving her huge portions. But let me put a chocolate bar infront of her and it's gone in seconds lol. Does anyone else's child eat like a snail or is it just mine 🤔
