Unfortunately it’s just him exploring his world. I have similar gap and mostly spent the time referring but it does get easier.
My youngest now 2 loves taking stuff out of boxes or tubs and putting them back in again, or getting all the toy cars and hiding them under the footstool or table and then putting them all away again or putting them down a ramp, eldest nearly 6 sits up at the counter colouring or playing lego.
M youngest also likes this little pop up play tent and hides in there with toys.
I know how you feel it’s cobstantly putting stuff away getting stuff out while trying to fit in jobs, but also the difference in 6 months time is huge so I’d try and have a sit and play for now x
