I usually cook dinner every year at my house for Easter. It's a tradition I started in my first year of marriage and I love it. I was in Aldi's the week before Easter and saw a kit to build and decorate a bunny house for $7. It looked so cute and I immediately thought it'd be a great way for my daughter to stay busy while I cooked and cleaned.
I was right. She loved helping her Daddy decorate the bunny house. Sure, it wasn't the most beautiful work of art, but it made a great centerpiece at dinner and the family loved it! It was a nice touch and worked for me to keep her little hands busy while Mommy was busy!! I'm sure there's plenty of similar projects for kids at other holidays or you could make your own. Maybe it could help your little ones too!
