18 month old growth spurt

My daughter has only just turned 18 months and the last couple of nights, she has woken around 10.30pm asking for a bottle. Now she has not woken for a bottle for as long as I can remember, not this year I don’t think. Could she be having a growth spurt and has anyone else experienced similar at this age? She’s never been a big eater but she was definitely hungry as she sinks the bottles so fast
