SIDS worry for premature baby

[Flowermoon90]

Hi,

First to give you some background information, my DD was born at 35 Weeks + 6 days (since I had a kidney infection) and we spent 5 days at the NICU for 5 days, mostly because of her jaundice.
She was both breastfed and formula fed for the first 6 months.
She sleeps next to me in her own cot, and my husband sleeps in another room.
My husband is a smoker (around 5 to 8 fags a day), but he never smokes inside the house, and washes his hands and brushes his teeth afterwards.

Even though DD is 9 months now, I'm still so scared of SIDS, especially because I'm the breadwinner, and my husband spends more time with her. He's really doing his best. Due to his depression and anxiety, I know he just cannot quit right now. He's already feeling really low. But I sometimes I hate him for smoking, and then I hate myself for it; On top of it all, this SIDS worry is driving me up the wall. Needless to say, I'm not having the best of days.

What can I do?

I might be wrong but i think the main reason for smoking and sids is when bed sharing and breathing on the baby. Smoking obviously isn't great when you have a baby but if its not in the house and he's washing his hands etc i think the risk is minimal. Sids risk drops after 6 months aswell
