Max did the same thing!!!He would jump and put his feet in the holes of the babygate to climb out!I zip tied a piece of clear plastic to the baby gate,so he couldn't put his feet in the holes and climb out.I got the clear plastic at Home Depot,it is actualy a 2x4 lighting lens,they only cost about 6 bucks,here is what I used....
23.75 In. x 47.75 In. Prismatic Clear Polystyrene - 1A25001A at The Home DepotYou just need to cut it to the size of the gate.It cut's very easy,with a razor knife,or sharp scissor.I just drilled four holes in it and zip tied it to the baby gate. You can probably use plexi glass too,but I think this works great, and is very inexpensive!!!
