3 year old constantly eating

My daughter is 3 and in the past 2-3 weeks from the time she wakes up and until she goes to bed at night she is constantly eating which isn’t something she does. She usually will eat a few bites and be done. She has been eating adult size portions and still wants more. Is this a growth spurt? Her past growth spurts she has ate more but nothing like this to the point where I’m concerned. Is this something that will pass or should I call her pediatrician to get some advice? I give her what she wants to eat and never take any food away or tell her she is eating to much because i was raised like that as a kid and it caused problems for me as an adult.
