Hi Lizaveta,
You most likely aren't doing anything "wrong" at all! There are multiple ways to work this and you just need to find a way that your daughter responds best to.
What I would do to possibly see some short term results that will still be fun for your DD is to create an initial customized file with pictures of very familiar, meaningful things in your home (favorite people, toys, etc). If you have a microphone headset or one on your laptop, you can even record your voice announcing the items. I would continue to play your daily lesson plan and also fit in that particular customized file/lesson a couple of times a day until mastery. It might take a week or two, it might take longer, but stick with it. Also, if you have only been watching the digital version, try to print out some LR files and see if she prefers being flashed the physical word cards or multi-sensory lessons versus the screen.
You can also print off flashcards or her favorite toys and match them up (we especially like our animal figurines for this game), or do word matching. If she is not adverse to "testing," for example you can hold up the LR print out flashcard that says "cat"....then put two other cards on the floor "cat" & "dog." See if she'll give you the correct word after looking at the matching card in your hand.
Have you tried labeling items in your home and taking her around to point at the words? (bed, table, cabinet, chair, etc.) Reinforce those words with a matching LR file.
Do you currently have your computer hooked up to a big TV? That is ideal, the bigger the better if you choose to go with a screen over printed flashcards.
With my daughter, we used the daily curriculum and just moved through LR categories that were printed off and used until mastery. She enjoyed it and didn't find it tedious, once she was solid on them, I printed off another set, usually every Sunday or so depending on how faithful we were. So, that approach might work for you as well.
Lastly, do you really believe that she is capable of early reading? That is essential, she
will pick up on your emotional cues, spoken or not. Kids are amazing like that! So affirm her and yourself with a bright, positive attitude and really believe that she can and will read when she is ready!
Most likely, she knows many words but simply has not shown you.
