Can language shift be reversed in Galicia?

Galicia is an autonomous community that suffers from diglossia as they speak two different languages that tend to be used in different contexts: Galician and Spanish. Whilst Galician has managed to survive many years of oppression, it has started to show signs of deterioration, especially amongst children and also outside of the family home. As a result, the use of Galician has decreased significantly, as seen by the 2011 census. Due to this, the government have intervened and started to put procedures in place in order to save the language. This includes reforms in education and attempting to ensure its use in all domains in order to help it gain prestige. Furthermore, they have introduced linguistic laws, which include allowing citizens to choose between the two languages and to increase the amount of Galician used, with the hope that Galician will be able to enjoy a similar amount of prestige to Spanish. These measures have only been implemented in the last twenty years but have they been put in place too late? Galician has only recently been oppressed due to the Civil war, when the use of this language was forbidden and there were severe consequences towards those who spoke it. Therefore, is it possible for Galician to lose its status of a minority language and to become the main language spoken in Galicia once again or has it lost too much prestige to be viewed in this way.
