So I know all moms have this same thought about their kids: "This is my favorite age/stage!" Then the next developmental stage come around and it's "No, this is my favorite stage!" It goes like that at every turn. Looking back, I have to admit that my actual favorite stage was around 14 months old. Busy could walk, talk and communicate all of her feelings very well. Everything she experienced was new and she loved every second of every day!
