DS can push off the table with his feet when he's in his Stokke. Sometimes it glides backwards but a couple of times he's actually rocked it back on it's feet, and I had to rush forward to stop it going over. Well, I'm not certain it would have gone over but the front of the chair was off the ground. The seat is at the right height for the table surface - it's a kitchen table so drawers/sides underneath the table top IYKWIM).
Any suggestions?
Thanks in advance
