Sids possible trigger

Why did I have to look it up now I can’t sleep all I want to do is watch over my son. Why did they say it’s more common in boys and baby’s born premature and low birth weight why did I have to freak my self out. Any words of encouragement I read that breast feeding helps lower the risk of sids and so does putting them in their own bed but I feel more comfortable with my baby sleeping with me in his own bed I know some ppl don’t believe in bed sharing which is fine each to their own. I bed shared with my last one and she will be 4 next month and I can’t get her to sleep by herself 😂😂. I just feel more comfortable with my babies close to me as I wake up easier when they cry and also it makes breast feeding so much easier and also I make sure not to put to many layers on my little man to make sure he doesn’t over heat.
