With the crafts, i wouldnt even bother to include your baby, they are useless for craft time until at least a year. So maybe you could organize small activities when baby is sleeping? I find most boys dont like the crafty stuff as much as girls do, such as beading, glitter etc. Maybe making masks out of paper plates, or paper hats you could decorate, like a pirate's hat?

Dont forget to make the 3 yo help clean up the toys and house many times a day or else you will find yourself doing lots of picking up after him!

I DO NOT tolerate biters. They get a BIG time out and of course mommy and daddy are told about it. Who does he bite? You?? Not the Baby?!?!?
