From www.funathomewithkids.com, it's "safe for babies and toddlers to taste (NO salt!) and it's also ready in less than three minutes. If you know anyone who's got gluten sensitive kiddos - we think this playdough is AWESOME!
Oh and PS - hidden benefit of being salt-free? Your hands feel awesome, soft, and moisturized after playing with this dough!
