Need help

Km

So, I had my first baby Sunday night 10pm.

We were released two days ago and before we were let out I had baby on my chest, he was sleeping and I had my eyes closed, (just done nursing).

A nurse came in, and said, "you know that's how SIDS happen, right?"

I was flabbergasted and by the time I processed what she had said she had left.(thanks exhaustion).

Now I am so paranoid. I cannot sleep a wink without worrying. Have not slept since this happened and it's starting to effect me.

Any tips? Tricks? Advice?
