So I have typed and done reserach for two posts in the last month, but I forgot to hit saved both times...hmmm...having a one year roaming around can be very counterproductive when you are trying to get a blog going.
First of all, I had done a little studying about baby mattresses. I was so confused when we ordered our daughter's mattress from Diapers.com; we just picked one and left it to chance. It turned out to be a great mattress after all, but when a friend asked me about the details so she could buy one for her baby to be, I didn't have an answer for her. Well, now I do. In a nut shell: 1. safety comes first (obvious) meaning one must pick a mattress that fits snugged within the crib walls to avoid baby getting limbs stuck between mattress and crib walls. 2. Coil mattresses are a better option to foam matresses, but truth be told, babies will sleep on anything so don't stress about it. If going with coil, the higher the coil count the firmir the mattress and the most comfortable too --once again, babies don't care a bout comfot and they will outgrow the mattress way too soon so no need to stress about it. 3. One other option is organic mattresses, unlike synthitic ones, they don't release any fumes that can cause allergens. Typically they are more expensive.
Personally, I would rather get a better quality coil mattress and add an organic waterproof mattress cover to go over it. But, As alway I have attached a few links so you can decide for yourself.
