Hey all, so how do I get my toddler to start climbing his high chair? He wants to when he's signalling he's hungry.... but maybe he's too young or too short?

We have a Keekaroo with the floor plate on the highest rung and his feet still don't touch because we still have the infant insert in. so he definitely can't reach so high to be able to pull himself up to that highest floor plate...

should I move it down so he can start practicing climbing or wait until he grows into it? or is he ready to start sitting without the infant insert? we don't strap him in to other seats without an insert...

He's 13 months old, active baby, almost walking, baby led weaning, 29 inches tall
