Aw! We had the BEST times when my dd10 and ds9 were that age. We went for walks, we cooked together, we went to the zoo, the park, the grocery store, playdates, Music Together, water table, storytime at the library.
Nothing really that was a curriculum but we made sure that every day had something new in it.
Those days are long while you're living them but so short looking back. I wish I had a time machine to go back and enjoy a day like that again!
