Generally, you can choose from three kinds of changing tables:
wooden ones with guardrails
hinged chest adapters
Hinged chest adapters are not recommended — dressers with these adapters have toppled over when a baby's weight was placed close to the outer edge.
Babies can get hurt if they fall off changing tables, so they should always be watched closely.
What to look for:
A flat changing surface should be surrounded on all four sides by a guardrail, which should be at least 2 inches (5 centimeters) in height.
The surface of the changing table should be lower in the middle than on the sides, which helps keep the baby from rolling from side to side. A contoured pillow (lower in the middle) will add to the safety provided by the changing table's shape,
Wooden changing tables with rails are usually the least likely to sway or tip over when a baby pulls on them from the floor.
Fold-up models should be checked for sturdiness: When the table is open, give it a good shake.
A wire changing table should have a wide base so that a baby can't pull it over on top of himself or herself from the floor.
The table should have shelves or compartments for storing everything you'll need. This prevents you from taking your eyes off your baby while you look for that hard-to-find item.
Use the safety belt every time you change your baby.
Never leave your infant unattended even if you think he or she is secure.
Always keep one hand on your baby.
You should keep supplies within your reach, but out of the baby's reach.
Stop using your changing table when your baby reaches the age or weight limit recommended by the manufacturer, which is typically age 2, or 30 pounds (13,607 grams).
