Can my first child’s mattress be reused?

Absolutely not. It is always advisable to buy a new mattress with non-allergic and antibacterial fabrics that do not irritate the child’s skin. If you pass on your first child’s mattress to your second child, this is not very hygienic as the presence of organic fluids that have filtered down to the inner layers creates the ideal habitat for mites and bacteria, which is unhealthy.
