Cheerio necklace - you will need fairly thick string, multi-grain cheerios, scissors.
This is more for you to make and them to wear. Today we got bored and made cheerio necklaces. I discovered they are good to make adult sized. I sit on the floor while he plays and he stops to take a bit. I also made one for Bear to wear (supervised as these can probably be a choking hazard) and he liked taking it on and off (repeat).
Just string 25 on and let dangle! You might need to show them how it works, he just kinda looked at it before understanding he could eat it. ha
