I feel guilty some days it’s more than others. I try to limit it . I read him and my 8 month old books, I try to get 2 yr old to color still not into it. We imaginative play with his little people toys or kitchen, do learning, he knows alphabet and counting 1-10. We listen to music and dance, take him to playground when I can. Some days I cannot depending… do bubbles, car rides he requests sometimes. I still have mom guilt as I feel I’m not doing enough cool learning activities.
