Answer: I had a baby die of SIDS when she was 5 months old and she was on her back, as was 90% of the mother's babies that are in my SIDS support group. A baby can die from SIDS in any position. There are mothers in my group that lost their baby while in a car seat, stroller, swing, being held, even two that were awake and not even sleeping. You cannot do anything to prevent SIDS because it is not preventable all you can do are things that to help reduce the risks. Everyone (except for people that have actually lost a baby to SIDS) is all caught up on the position of the baby when sleeping. There is more to it than that, like I said most of the mothers in my group had their baby die on their backs. I was one of the many mothers that thought I had nothign to worry about because I put my baby on her back to sleep, didn't smoke or drink, I did everything I was supposed to but in the end it didn't make a difference. I know now that there are a lot more contributing factors since I have had it happen to me. I spent the first year after my babies death doing nothing but research becaus I need answers since I did what was supposed to and it still happened. If a baby is goign to die of SIDS there is nothing you can do to stop it, prevent, or even detect it. You can not prevent something when you don't even know what causes it you can only do things to help reduce the risk of it happening. In the end you do what is best for your baby. I have had two kids since my baby died and they both slept on their tummy, back, side, however they wanted and they are fine. There a couple of mothers in my group whose babies where over six months when they died and when a baby starts rolling over on his/her own you cannot stop them from sleeping how they are comfortable. You just have to leave it in Gods hands and live your life because if you sit around and worry about it you will miss your baby being a baby and before you know it they are teenagers. That's what I realized really quick with my first daugther after the one I lost. For the first month I had her on an apnea monitor and constantly watched her sleep. Then I realized what I was doing was not good for either of us. An apnea monitor is only good for apnea. If a baby stops breathing because of SIDS that baby is already gone because a baby that stopped breathing due to SIDS cannot be revived. There is no such thing as almost dying of SIDS if it is SIDS your baby is gone. I took my daughter off the monitor and a few months so she could sleep without all the wires and an alarm going off because a lead came lose and waking her up. I stopped worrying about it and just decided to enjoy her. My son, who I had 2 years after my daughter, I have never once worried about. It is out my hands so I just do what makes my kids happy.
