Are most 2.5yr olds obsessive? DS gets onto one thing and will keep at it until I remove it. It doesn't matter how many times I redirect him or tell him not to do it he just keeps doing it. It's usually opening drawers, climbing on chairs etc, touching the DVD player, it can go on for days or weeks and as soon as I get rid of what ever it is he finds a new thing and it starts all over again. Today it was taking his shorts off repeatedly. Is this normal? How do you handle it.
