Ok, so they aren’t actually bags, but that is the most common name for these sensory, Reggio Emilia, Montessori, open ended play, educational, and creative inspired toys.
A friend of mine was given one of these from her Mother-in-Law and I immedialy recognized the snack cups! Head over to the Dollar Tree and pick up a package of these snack containers. Two for a dollar, so don’t buy them from Amazon!
You will need to drill a hole for the mouth. Start with a 1/16 drill bit and work your way up to 1/2. My twins are 19 months and despite their many attempts, they could not manage to get their fingers stuck in the hole. It was just a smidge too big.
The correct size of pom-poms is paramount to this working. I had two sizes that worked but I’m not sure size they are. I’m thinking either the 1/2″ or the 10mm for the larger one and either the 3mm or 5mm for the smaller one. The smaller one fit through easily but the larger one took a little more concentration to squish in.
