This is an easy and fun game for baby. Take a laundry basket put some balls in it and a little pillow for his back. Put the baby in it.
Always keep an eye on your baby, especially if he moves a lot as he can flip over the laundry basket. both of my babies loved playing in the laundry basket, when he was able to walk my oldest one was taking books and was climbing in the basket to read. You will need an other basket for actual laundry !
