This one is like a 30 second DIY. My son likes to make noise a most kids do. He also likes to put things in his mouth. He also likes new things. To keep from going crazy with toys and rattles I make him rattles. Super simple.
Whenever you run out of a creamer bottle, Parmesan cheese bottle etc. just add beans or rice into the mix. This will make a ton of noise, wont break open, and will be a nice chew toy for you baby as well. When they are bored with if, just throw it away and start a new one.
It is simple easy and fun!!
