There are so many things you can do, depending on how much money you want to spend. If you want to keep costs low you always can do some decorations yourself. I painted few pictures for my daughter's room but if you are not very into painting you can make something out of paper like dream catchers and hang them on the lamp. We decided to dedicate one of the walls for a mural but again if you don't want to paint you can make paper butterflies, flowers, castle, etc. and stick it on. It?s a great fun especially when doing it with your child they always want to help :)
