arusha - My son loves LR but there were moments when he just did not want to have anything to do with it. I chose to take a break for a week or two. It worked for us.
I sometimes, turned LR on while he was having his snacks, or before bed. I carried him (standing up) in front of the screen, and did actions shown on the Multisensory lessons. He also loved to see real objects related to the words he's viewing. I would garther things up in front of the screen and showed him the objects while the word's being displayed. He loved it then and still loves it now.
Hope this helps.
