Can I trust any of the baby/toddler products I buy from Greenhills Mall?

I guess it's not really bad if you buy there on several occasions. Just make sure that the items aren't faulty, especially the battery-operated ones. Make sure, too, that all parts aren't loose or else there would be a risk of choking. Also, it's good to consider buying only the BPA-free ones as there are some toys, specifically the ones made in China, that contain this forbidden chemical for kids.

I'd suggest buying the necessities at a more reputable distributor, but there are some in the mall there. For important purchases, stay with what's safest and don't take the risk!

Considering Green Hills' reputation. I'd say, stick buying baby products from well known boutiques in malls.
