Do you know any of the many differences between an adult mattress and a baby mattress? First of all if you don't know some of the main differences then you need to read this and understand it completely. The reason you need to know the differences between an adult mattress and a baby mattress is because the differences are astronomical in both the short term and long term health of your baby.
Most parents think it is ok for their child to sleep in their bed with them and truthfully it can be as long as you have a firm mattress. If you are sleeping on something that is very padded and can cause your child to choke because of the padding then it is not safe and you need to get them their own mattress.
The biggest difference in mattresses between adult mattresses and baby mattresses is the fact that the baby mattress comes at a set firmness that should not be modified. Many parents think they can put down more padding and even add blankets under the sheets but this can cause problems. There is a difference in firmness for a reason, so don't mess with it.
Another difference that is very easy to spot is the size of the mattress. The reason it is easy to spot is because there is one standard size for infants and babies and that size is 58 inches long and 28 inches wide. They come standard at this size because they are made to fit a child's crib and then be transferred to an actual bed. If your child is sleeping in a crib then it is recommended that you get this exact size of mattress as opposed to finding something non-standard.
These are only some of the differences between adult mattresses and a baby mattress, but just know that things that affect your child are usually not known to us adults simply because of our size and our development level.
