Baby rolled out of bed

I left for work this morning at 6:20 and my husband called me at about 7 saying our 9 month old rolled off the bed 😢. Last night was the first night I put him back in bed cause he was constantly getting up (teething badly) and so well I needed some sleep cause I work 12 hr shifts as a nurse at a hospital. Brought him to the ED at the hospital I work at and he’s been acting totally fine, no vomiting/loss of consciousness, taking bottles and solids as normal. But I just feel terrible ( and I’m not even the one who was home!) our first child has co-slept since 2 months and this has never happened to him! Ugh please someone tell me I’m not alone!
