Ideas for entertaining very energetic 9 month old!

[OctopusLimbs]

My little girl is 9 months. She is very, very energetic and active - she is into everything and just never stops. I find very few things keep her interested more than twenty minutes, and when she gets bored she gets grumpy!

I would really like some help with ideas for things to keep her entertained, so I can rotate different things to occupy her. I particularly would like things I can do indoors with her when the weather is bad.

We already go to soft play, go to the park, go to baby groups and activities (although many stop over summer), do playdates with other mums, have time crawling around different rooms to explore, play with toys (although recently she shows little interest in proper toys), explore treasure baskets, go swimming. I can't really go for walks with her in her stroller any more because she gets bored and cranky after 10-15 mins, and just keeps twisting around trying to escape.

I am exhausted with trying to keep her entertained! She's just a little whirlwind of activity...

We had a lovely book called the toddlers busy book that just had loads and loads of ideas. Some were better than others but there were some real gems (which I obviously can't remember or get off the sofa to find the book to look up)

Pop her in the kitchen sink with a couple of plastic cups. Blow bubbles and have her chase them. Inflate and deflate balloons. Dance. Bounce on the bed. Massage her.as she tries to escape. Read books with bright pictures. Show her family photos and tell her all about the different people. Get out scarves, feather boas, all different fabrics etc and let her explore the various textures. Shake dry pasta in an empty dried out plastic bottle. Disco ball in a darkened room.

My daughter is the same age, we do lots of sensory and messy play. Pinterest is fab for ideas.
Sensory bottles filled with different things, oil, food colouring and water, feathers, shells and sand, buttons, waterbeads.....

Paint, cornflour slime (amazing stuff), shaving foam, cooked coloured pasta/spaghetti, Jelly, (I add toys to it sometimes, so for instance shaving foam
with some toy penguins, green jelly with dinosaurs in). I have a builders type tray and I just strip her off and put her in with what ever she's playing with.

We've just got her a small sand and water tray for the garden too, which she loves.

The pushchair thing, I wouldn't stop going for walks. My DD did it a few times, but I just carried on walking and talking/singing/pointing things out to her and basically ignoring it. She seems to have stopped for now.
