She's doing it all the time, I have to sit her back down about 10 times a meal. Its a Tripp Trapp, and she's little, so slips her feet onto the seat and stands on that. We dont have a harness, to be honest I think she'll just garotte herself on it if we got one.
Its driving me absolutely mad, I ignore a lot of stuff but really can't ignore this, if she falls its a long way down.
We are trying the calm consistent "sit down" and sitting her down, but its really starting to ruin meal times. And I cant help but shout occasionally - like when she actually gets onto the table...
