Is it supposed to be so easy for a child to remove the baby set while sitting in the Tripp Trapp or is ours broken? My toddler keeps pulling it up and detaching it. Or is my toddler just too big for the baby set? She is 28 months but with a gross motor delay and can’t climb on and off it herself yet so we still use the baby set. Still too short for a normal chair too and also can’t climb off and on a chair either.
