Ah I’m so jealous of the multilingualism! The twins are bilingual and I think it does something amazing to their brains… Although we are noticing some impact on Issy’s reading. Five nights out of 14 they’re in a house where they only speak Spanish and sometimes I can see their brains ticking around words when they come home. Seba will often call out in Spanish during the night.
I think you’ll find this unit interesting, given your background, and I’m looking forward to any insights you can offer about other GLAM contexts!
