I had a hard time with this one for multiple reasons. My son is our last "planned" baby. Right now at least, we don't have any plans for another. My husband and I don't know if that will change, but we are content with not having another baby right now. So my son turning four was hard. He officially isn't a baby or toddler anymore.
Another reason this was a hard birthday was because the planning. PJ Masks is a popular theme. There wasn't very much décor out there that fit within our budget. I agreed to do this them before I knew this, but thanks to Pinterest, I found a ton of DIY décor ideas. I don't know about other people BUT when I make things myself instead of buying it, that means more stress. My mother-in-law did help me by making his homemade PJ Masks shirt.
