How clingy is your baby?

You may have to gradually get him used to not being held while you're doing stuff. Like start with letting him cry for 5 minutes, then 10, then 20, and then you can stick with 20 minutes each time of which you can do something and he should get used to that time frame. There's no guarantee that will work though!!! Or, you can put 90% of his toys away. Leaving only 10% out at a time, and rotate them so that it's like new toys each day or week. Maybe that would entertain him?? My son loved his Fisher Price Jumperoo. Maybe you can give him a munchie, like a teething cracker, something that he can work on for a while when you've got to do your stuff.
