Advice standing baby

So

So my baby has gone from standing to falling on his butt and then backwards on his head a handful of times.

I really don’t want this to keep happening but I can’t be by his side every second nor can I always strap him into something. I have a toddler and need to cook and clean and baby needs exercise too.

I do always have my eye on him but can’t always break his fall quickly enough.

Any advice for me plz.
