Increase in toddler’s appetite

Ch

I wonder if my now 3 year old is going through a growth spurt? Lately he’s had such a huge appetite! He already ate an entire banana and 3 scrambled eggs this morning. Yesterday he ate a large amount as well! I love that he has an appetite, because he used to be just a picker. Oh and some days he eats hardly anything but the days he does eat, he goes to town! Anyone else deal with this?
