Have you got a play gym that your little one can climb on? Put some soft cushions around the bottom of it just incase.

When she climbs on the table, tll her that tables are not for climbing on and then direct her to her playgym. Positive redirection is a very effective way of gentle behaviour guidance. Even though she is only one, children can understand alot more than you may think! I used this alot when working with babies in child care Toddler LOVE sitting on the tables)

If you just keep repeating this technique I guarantee it will work .... eventually (however you might be old and grey heheheh)
