Any tips on getting my 18 month old to STOP climbing on chairs and then tables !

[hellowee]

I don't know how to stop him. It's constant and never stops.

I must remove him from the table / kitchen island 50 times a day.

Does he need an indoor climbing frame ?

He gets the chair, climbs them and then on the table- on repeat.

Any tips ?? It's SO annoying.

I remove him and tell him no, but it just continues.

He goes to nursery three days a week. He has plenty of outdoor time too. He has a slide outside he likes to climb up on etc.

It's so frustrating !

My DD is 18m and the same. Our stools are folding ones so not very stable either. But I do let her climb - I keep an eye on her and warn her to be careful and she does take care to be fair. Occasionally she falls and cries a bit then she's up there again a few moments later. We opened up the stair gates a few months back and she climbs up and bumps down stairs independently - I've no concerns about that.
We have a Piklar triangle but not much space to set it up at the moment - honestly though I suspect she'd still prefer to climb over furniture anyway.
