The Bottle Let Me Down

Before I go to bed, I have to come clean. My husband caught our daughters drinking cough medicine and ibuprofen tonight. One was feeding it to the other.
I can't even express the sickening feeling that ripped through my body. I feel shocked still and it was several hours ago. Poison control, as well as my 500 searches on the internet, claim that it wasn't nearly enough to do any harm.
I left the medicine in their room. I totally under (over?) estimated them. I would have bet they wouldn't drink it and a few weeks ago I would have been right.
I can't stop thinking about how suddenly after turning 3 they are so independent and it just breaks my heart that my babies are gone. It's been a rough few days with the soothers going, the big girl beds, colds and then mommy trying to poison them. It adds up, you know.
Whew, I'm tired. Tomorrow I will try to be a better parent.
