Sudden Infant Death Syndrome (SIDS) is a syndrome marked by the symptoms of sudden and unexplained death of an apparently healthy infant aged one month to one year.

Since I've had experience with two kids so far, I have always been afraid of a certain syndrome that I have read in one of my baby books during my first pregnancy, and it still bothers me to this date. It is what we call "SIDS" which stands for Sudden Infant Death Syndrome.
Thankfully, I never have been unfortunate enough to encounter anyone who have had experience with SIDS, but it still is a scary thought.

I have read many ways that could prevent SIDS (although it is never guaranteed) and I have always done my best to follow all suggestions to the letter, like how I position my baby while he's sleeping and the likes. Just recently my son turned one, and it was definitely a huge relief for me, that finally I can relax again and stop obsessing about it, but another baby is coming next month and I'll be back to square one all over again.

Is it abnormal to have these kinds of fears? I seem to be the only parent who worries so much about this, I've met a lot of new parents who are not even aware of SIDS, and here I am spending every minute of my days worrying about it.

What are your thoughts regarding this? Were you scared as well, or am I sounding a little coocoo to you?

It is not good for your baby to have such thoughts as it will affect him/her health . And is not good for you ,too since you need to be calm and optimistic in order to have a smooth parturition.
Just hope for the best and trust in God or whatever divinity you believe in that everything will be fine and nothing bad will happen to you or to your baby.
If you'll keep worrying all day long about this , you cannot change anything for better , on the contrary.
