Both of my children have had more interest in what was behind cabinet doors than they were in their toys.
We didn’t want them to get hurt on anything, smash fingers, or break dishes, so we bought these cabinet locks, and they held up really well.
My toddler pulled down on them so much that they only came off the cabinet because the paint gave way. A little super glue had them holding again in no time. The locks themselves were very sturdy.
