Bisphenol A, or BPA isn’t new, but lately we’re being exposed to it in much larger quantities. It’s now in
plastic bottles (including baby bottles)
the lining of tin cans (including baby formula) ,
thermal paper (often used to print receipts, so don’t hold them in your mouths while you sort your change)
carbonless copy paper
you (the CDC found it in the urine of 93% of subjects tested) 
Some studies have linked it to hormonal problems, obesity, neurological problems and more, while others claim it isn’t harmful in small doses.
While they figure it all out, I figured out a way to reduce BPA exposure at home.
I have a water filter at home. Rather than store the water in plastic bottles in the fridge, I now use empty wine bottles and have also recycled a beautiful bottle of port.
My daughter was against the switch at first. She liked using the lightweight plastic bottles (so did I), but yesterday she commented that she prefers drinking water from glass bottles better, and she’s right. Water tastes better poured from glass.
When you’re half asleep, eyes half shut, and you want a sip of water before bed, watch that you don’t surprise yourself with white wine.
If, like me, you’ve totally failed to teach your son not to drink straight from the bottle, accept that he’s going to look like a wino.
