Postpartum anxiety. Please help!

My anxiety has been really good up until a few days ago.

My baby is 14 weeks old today and an article popped up on my Facebook that said that SIDS peaks at 3 months and I’ve been terrified ever since.

The article said nothing about why it peaks then, it was just horror stories.

Can anyone tell me why it peaks at 3 months and why it happens?

We have her in a bassinet by the bed, no pillows, no blankets, humidifier, temperature set to 68 degrees.

I’ve been having trouble sleeping since I read the article.

How do you get past the fear of SIDS?
