Toys for 9 months plus? Don't want to waste money!

[goolish]

DS doesn't have many toys, he has stacking rings, stacking soft blocks, baby laptop, mini keyboard, one of those activity blocks and standing thing. That's it! Any suggestions? We're obviously at home a lot at the moment, and I want some new stuff for him but toys can be expensive and I don't want to waste money. Any ideas welcome!

I'd get a tray to play with water and plastic toys in, a pushalong toy vehicle of some sort, a baby doll, a collapsible tunnel, a soft ball, stacking cups and some play scarves. My youngest is just 1 and loves all of those and shouldn't cost too much.

Cardboard boxes, a hairbrush, your spoons and Tupperware, plastic cups, an old handbag, a splashy bath in the middle of the day, a pile of clothes that you can hide in and wave and tickle him with, songs on the radio you can clap and dance to, empty bottles filled with a sprinkle of rice and a few dry pasta pieces
