Since becoming a mum I've given up wearing anything my kids can break. That doesn't mean I can't wear jewellery, but I stick mostly to things like polished gemstones on a silk cord, or bead necklaces and bangles that are specifically designed to be fiddled with by breastfeeding babies. Some of them are made of silicone so kids don't chip their teeth if they bite them. It's a bit limiting though. I do like to have a necklace to fiddle with through the day.
I used to have pierced ears but I prefer dangly earrings and that's just asking to have them pulled on by little people, so when the holes closed over a while back I didn't re-pierce them. I'm sure I will one day.
Scarves are nice too, thought there's not a lot of call to wear them in Brisbane.
