Magnatiles! They keep the kids busy for 30-60 minutes while we're prepping dinner and setting the table... they are worth their weight in gold!
The one problem with them is that Charlie will build something and then Olive will knock it down. But in a minor miracle, he's gotten really good at using his words to express his frustration (as opposed to whacking her, which is what he used to do). So Magnatiles still works to keep them busy. And Olive is getting a lot more into building too, which helps a lot!
How do you keep your kids busy while you cook dinner?
