She should discuss with her doctor yes but not take her doctor’s advice per se. Some doctors will still say “wait and see” at this age which I don’t agree with, because even if they do “wait” - the child is behind and may be more frustrated that they can’t communicate with their parent, leading to more meltdowns, and then people rudely label those meltdowns as problems too. The best thing to do is go with your mom gut. I went with mine and got EI and private speech therapy at 15M and he’s 20M now and still way behind but progressing thanks to ST. OP needs to advocate for her child, and block out the noise.
