What do you do to keep your kid busy while working at home?

We both get busy: me with my laptop and her with her toys. I don't care how much mess she will make as long as I can have my work done and that I'll just fix the house once work hours is over. But of course I don't simply leave her with stuff. I make sure that all that I leave with her are safe (no sharp thingys scattered, not baby-friendly clutters are swept aside, nothing will spill except her bottled milk, I position myself that I can see what she's up to etc.) And then of course when it's meal time, I put everything down and feed her and make some time too. You know working at home with baby can sometimes be stressful but it's all worth it if you're able to do your work without compromising your bonding with your child. And for sure to those whose kid is older (than mine who's just 1) they know better how to handle the situation and they're more likely the experts now ;)
