Sleep is incredibly important to babies, and a good baby mattress will help improve the quality of their sleeping hours. The good news is that unlike clothes and many of baby’s other items, a good baby mattress will fit your child for the first 18 to 24 months of their life – so you won’t have to worry about your child “outgrowing” the mattress before you’ve gotten a worthwhile return on your investment. Also, remember that sleep is crucial for your child’s physical and mental development during this period – miss this vital period of growth, and there’s no turning back the clock. Here’s something to think about – according to studies, around 25% of young children are afflicted with sleeping issues, and these can turn into excessive daytime sleepiness and other concerns as they grow up.
