Here's a really simple idea for a sort of homemade baby gym that even the littlest babies can enjoy.
String up a line of balloons and sit them or lie them underneath! As you can see I used the bottom of our dining table, but you could use two sturdy chairs or adapt a mobile or existing baby gym.
(yes, they are Happy Birthday balloons, good thing babies can't read!)
I filled some of the balloons with rice and dried lentils so they would rattle and shake when kicked and swiped at - adding an extra sensory aspect to the playtime.
The would be lovely for crawlers to travel through, you could cover an entire table in balloons and create a magical crawl tunnel!
You might notice I have no pics of babygirl actually playing with the balloons, that is because she hated the whole idea - as you can see my big kid loved it, so I'm not calling it a complete playfail!
