One of our faves we learnt from a friend,
Make an obstacle course in the front room..a tunnel toy or crawl under a table, stepping stones you can buy or use cushions or even sheets of paper if the floor isn't slippy, a bucket to throw balls or bean bags into,
A piece of string on the floor to try to balance along...then do circuits...can yoi do it backwards/on one leg/ faster etc it gets their energy out :)
Grab a cheap second hand gym ball...fun to roll to each other or to sit on with him and bounce or help him roll on his tummy, lots of ways to play.
Hide and seek (very basic and won't last long at this age but its fun and different).
Walks with torches are also faves here. Walking in the dark looking for Xmas lights are fun this month. But mine also loved just holding a torch and shining it at hedges telling me they had found giant spiders or other terrifying bugs 🤣.
Cooking. Its a pain and messy but they love to help bake. Things like mug cakes are an easy win on dark evenings.
Baths are a good send, you can mix it up with different games - toy car wash, squinty bath foam- glowsticks or light up bath toys.
Invite a mum friend and their little on over...dissolves the length of time and loneliness .
Big hugs, it does get easier. Xx
