A new level of functional crafting

My baby girl loves the Jenny Jump-up seat at her baby gym. So much so that my husband wants to buy one for our house! BUT, considering we have a tiny house and limited funds, it's something I can't personally justify.

HOWEVER...

You can make your own baby swing!

Gotta admit I'm a huge DIY fan, but this never occured to me.

What do you think? Would you make it?
Would you put your baby in one that someone else made?
