Going for walks, cardboard boxes, walking round the furniture, reading stories, put pasta in plastic bottles rattles with different sounds, if all else fails, a bath even in the middle of the day. Theres a series on CBeebies iPlayer called Baby Club which has an At Home series which they did in lockdown to show lots of things to do with baby at home. I'd recommend that - you can even watch with baby as they have songs and stories on that. A cloth bag with a toy in you can explore together. Have fun!
