While working from home, I found my 2 year old wanting to mimic my new "home office" lifestyle. Money is limited and I had a cardboard readily available, so I thought "let's make one!". One of my biggest pieces of advice when crafting for toddlers: you can make it nice, but remember they will destroy it, so just have fun with it.
Also, Google youtube videos on "how-to" make a cardboard laptop. Find what works for you. Here is the one I really liked.
Enjoy some pictures of Bean hard at work and melting hearts.
