Weedkiller Advice Please

Hi, I am hoping for some advice please. My boyfriend put Barrenttine Lawn Feed, Weed and Moss Killer all over our lawn last night. He also used about 8 times too much . We looked online last night and he soaked the grass through, in the hope that it would dry out and be safe to go on today.
My worry is that we have pets, a todder and I'm pregnant... could anybody please tell me whether or not our garden will be safe to use today?

 

It sounds a bit overkill to me ...I'd go with @Marleys advice.

 

Most weed and feeds containing herbicides have side effects which you can find on the safety data sheet.
You don’t want a granular feed getting into your eyes, ie children playing on the lawn and rubbing eyes.
The product also contains iron which stains, if you water it and step on the lawn then walk on patios or inside you will stain the flooring.
If he’s added 8 times the amount the grass will be damaged as it’s way over the limit.

I believe this is the data sheet you need to look at.
