The safety of a baby is always a mom's number one concern. To ensure your child is safe whenever it is laid down on its changing table, find the unit that includes guardrails and safety straps. Also, look for the table that has rounded corners to ensure your baby doesn't get caught on sharp edges.
Most small baby changing tables come with changing table pads to make babies comfortable. If your table comes with a thin pad and it doesn't feel cozy at all, simply get a replacement. A thick pad is recommended, but it shouldn't be thick enough that it has a height that's higher than the height of the guardrails. Changing pads are machine washable so throw them in the wash as needed.
What most moms do to ensure they get quality changing tables is only purchase from reputable manufacturers of baby and nursery furniture.
