Decorating the room of a child is easy when they cannot talk. As soon as they learn language, they have opinions. The nursery we set up was according to our tastes. When our little girl turned two she wanted specific things in her room. Of course, some of the things kids want are not feasible even if you want to give them everything. Our little boy wanted a 150 gallon aquarium for his room. He wanted to set up a saltwater tank. We agreed to buy ocean creature Singapore wall stickers while he saved for a smaller version of the aquarium he wanted.
His room was big enough to hold a 50 gallon tank without making it too tight of a space. He has maintained his interest in the ocean since he could speak, so we were going to make sure he had an aquarium to learn from. The big Singapore wall stickers were a compromise that helped him establish his space with things he is interested in. My wife and I are not even that fond of the ocean. If we swim, it is in a swimming pool only. I do not fish and neither does my wife. However, our boy is interested in all things aquatic. We encourage his scientific exploration even if it is not our cup of tea.
The visuals the giant wall stickers give to his room are symbols of his fascination with aquatic life and ocean ecosystems. He has cleared a space for the big tank he knows he is getting. We actually can hardly wait to get it for him, but it is something he needs to participate in saving for. A saltwater tank is not cheap. The wall stickers got me interested and I looked for ones about guitars. That is my hobby. I have a large guitar sticker on the wall of my office now.
