Not sure what do you mean by "already", but according to the ones we spoke - they are seeing a huge spike in demand this last year (which they correlate with masks and lack of in-person learning in very young kids).

[*] "Masks Can Be Detrimental to Babies’ Speech and Language Development" https://www.scientificamerican.com/article/masks-can-be-detr...

Couldn’t the spike in demand be related to all the articles talking about this issue?

I believe kids are better off in school and that the pandemic and response has certainly had an effect, but I can’t imagine that most parents would even know to consult a speech therapist otherwise unless suggested by the school as is usually the case.

I've never heard good things about ABA from people who actually went through it, so maybe this is for the best.
