I don't really have advices on how to work things with letters and reading with your little one because for us it went miraculosusly...but I will think about it!

I have a 3 years old. This is our reading and letters journey so far.

1..He knows letters from the age of 1 (we had some wooden letters and I didnt noticed he started to memorize them). All Letters from A-Z and backwards.

1. At 1yr and 3 he already could arrange letters of his name: CALEB. Plus other words like mama, tata.
2. At 1 and 8 mo he started to write letters. By the age of 2 he was already writting all letters (and numbers up to 100-150)
3. Now, at the age of 3 he can read short words and sometimes longer words. He writes many words from his memory, he can easily say which word begins with which letter and so on. His reading skills are great for his age. But it was normal for us. It was natural.

So I'm only saying this because I didnt struggle with letters, reading or words. I guess every child is different and his interest was always letters and a bit later numbers. They still are in the present.
If you let your daughter watch educational shows, you can try Alphablocks. Take a look when you have time. They are amazing.

other than this, I don't know what to say at the moment, why your daugther doesnt have the interest for words yet. I know a lot of kids who dont either. Maybe its not her time yet. But she's so good at pretend play, from what I've read! That is actually super great! Imagination and creativity are very important for their little brains as well. See?? My kid isnt quite creative. He's more into logical things and activities. So yeah, children are definetely unique and have different interests and abilities.

On the other hand, I wanted to say a big Welcome to you in this community and hive blockchain! I've just read all your posts, I wish you all the best in Mexico!
