hi there, we had the very same problem with our kitchen drawers. however, i stumbled upon safety latches for drawers from Ikea. they attach to the side, rather than a top support beam. and the best thing about them is that they have a catch, so that once the drawer is opened a little bit (maybe a couple of cms) the latch is caught, so that you cant push the drawer back in (to catch little fingers!), and of course you cant pull it out fully either. so my little man pulls on the drawer, it opens a little bit, but then cannot budge in or out so he gives up and moves on to something else! its easy for adults to open, just slide your finger in at the side and release the catch. and they were really cheap.
