Following yesterday's post here are a few of the activities I was doing with Otis when he was 18 to 23 months old. Age isn't so relevant, it's only a guide. It depends on what your child finds interesting, what skills they have and what skills they are working on. Children of this age are often more interested in gross motor activities - if your child at this age is more interested in moving and climbing that is totally fine too.
Learning to brush teeth (note low mirror).
