Never cointained my kids they just learn how to move it to the things i was trynig to keep them away from. I can to the conclusion that i should put the PET FOOD in the playpen, not the baby. Worked like a charm.
If i was iroing id set the ironing board and iron in the playpen. Like i said the pet food was in the playpen until they learnt not to touch it. Sometimes id use it to corner off the kitchen if i was cooking and i even out the tv in it for a while. Just until they realised the tv wasnt 'broken' and didnt need to be fixed with a toy hammer.
