Little Reader was the key for us, for sure!
The reason we liked it is because we can keep track of the lessons and steadily progress, and because of shortness and well-roundeness of the lessons. I would say it is more imporant to have a regular short well-rounded input every day, then long elaborate learning activity once in a while.
The secret, that I discovered with my children is to keep on going and have fun, and NOT THINKING ABOUT results. As long as you have input and make it fun, it should not matter for you that you do not see obvious results. Just keep on going.... and results will come in the most amazing way and probably when you expect them the least.
With my first child, she showed her ability to read at about 12 months, reading random complicated flashcards. Then she decided that she did not want to show what she knew, but we continued with Little Reader, because it gave her great phonics foundation and vocabulary. Then around 3 yo, she started to read on the 1st grade level overnight. One day she would not read to us and would show the wrong answers, the next day she took a simple chapter book and red it smothly and perfectly. She progressed rapidly after that and never went back.
The VERY SAME thing happened with my second child! We faithfully did LR, short and sweet every day, and showed lots of enthusiasm in dong it ourselves. He did not show his ability to read, excerpt for a separate words when he wanted

Then one day when he as 3 yo, he woke up in the morning and said Mommy I can read anything! And... he did!! He took his children's Bible and red chapter after chapter outloud.
Ever since we can not stop them
Our youngest at 1.5 yo loves reading as well. Differently from two older ones he does not speak fluently ( both older ones spoke fluently in full sentences since 12 month), so I can not gauge accurately how much he is reading.
One other thing that we did a lot in addition to Little Reader was Native Reading -- reading books together, while following with finger every word we are sounding out. We read a lot every single day more then 20 books per child. So that was a lot of native reading there.
We have not done anything else for reading, but all 3 of our LOs love reading and are good at it. And I am thankful for LR, that helped me to be consistent and for simple reading/bonding time together every day
you are doing great, so just continue and have fun!
