How can I apply ITIN for my kid considering IRS office is closed?

IRS is closed for months and still not sure when it will resume.

Since ITIN application for my kid could be only available in personal visit to IRS office, and normal takes 2 month long to be approved? Given such situation, How can I do to apply the INIT and file 1040 in time? The due date is July 15, may not have enough time to get ITIN ready before CA tax file either. 

Anyone has good idea?  Many thanks!
