BOSTON (CBS) – Advocacy group World Against Toys Causing Harm (WATCH) has put out a list of this summer’s products that could be dangerous for kids.

Some of the toys on W.A.T.C.H.’s list are not dangerous, except, Joan Siff said, when parents make the mistake they replace the need for parental supervision, like around pools:

“Floaties and water wings are fun for kids to use, but never replace parental supervision,” Siff told WBZ NewsRadio 1030′s Mark Katic. “A lot of time parents and caregivers make that mistake.”

W.A.T.C.H. Director Jim Swartz also says be careful in buying bike helmets.

“There was a recall of about 30,000 (helmets) just recently. Don’t assume that because you’re picking up a bike helmet that it necessarily complies with existing regulations,” he said.

W.A.T.C.H. says nationally hospitals expect to treat 2.7 million kids, and that many of those injuries could’ve been avoided.
